Version History of FileUltimate

Version 5.14.0 - October 12, 2017

  • Improved: Document Viewer:

    • Fixed: The below error which happened in some environments:

      The type initializer for ‘_UXg’ threw an exception. —> Could not load file or assembly ‘PortableEngine, Version=2.7.3.0, Culture=neutral, PublicKeyToken=a6f3cafa178e6038’ or one of its dependencies.

      The error happened either:

      • When ASP.NET impersonation was used via <identity impersonate=“true” /> tag in web.config

      • When Glimpse library (diagnostics & insights library) was used in the project.

      In both cases, the error is now fixed.

    • Fixed: Viewing some TIFF files caused crashing of IIS worker process.

Version 5.13.0 - August 28, 2017

  • Improved: DocumentViewer rendering accuracy and performance. Better text selection, cursor is changed to “text select” automatically when over selectable text. When pressed space bar “pan mode” is switched on. So behaves same as Adobe Acrobat.

  • Fixed: DocumentViewer and ImageViewer displayed black background behind pages/images in full-screen mode on recent versions of Chrome.

Version 5.12.0 - August 9, 2017

  • Improved: Document Viewer:

    • Fixed: Conversion of a large document could fail upon first view in DocumentViewer due to the default ASP.NET timeout (110 seconds). Increased timeout so that conversions that take long time are completed successfully.
  • Improved: ControlBase.StateId will not be random and will change less often. It is now calculated according to the url and control ID combination. This way more handler methods can make use of browser caching across different sessions. For example, image/video thumbnails will be more likely loaded from browser cache in consequent sessions for additional performance boost (no server hit even for HTTP 304 Not Modified).

Version 5.11.1 - July 31, 2017

  • Fixed: In Example Projects, although dependant NuGet packages DocumentUltimate, ImageUltimate and
    VideoUltimate were restored sucessfully, the DLLs were not copied to Bin folder because they were not referenced directly. Thus corresponding features were disabled in FileUltimate. Fixed the Example Projects to reference all DLLs so that all features work out of the box as expected.

  • Fixed: DiskCache should not throw exception when the cache folder does not exist yet.
    For new installations, image/video thumbnail generation and DocumentViewer were broken due to this issue
    (user needed to manually create cache folders).

  • Fixed: In view layouts other than “Details”, checkboxes were displayed over drag selection rectangle.

Version 5.11.0 - July 13, 2017

  • Added: Azure Blob File System. You can now use an Azure Blob container like a regular folder on disk.
    To create a root folder pointing to an Azure Blob container, you set the Location property like this:

    rootFolder.Location = new AzureBlobLocation
    {
        //Leave path empty to connect to the root of the container. 
        //For subfolders, path should be specified as a relative path
        //without leading slash (eg. "some/folder")
        Path = "", 
        
        //Get these values from your Azure Portal (Storage Account -> Access Keys -> Connection String)
        Container = "myContainerName",
        AccountName = "myAccountName",
        AccountKey = "myAccountKey",
        
        //Optional:
        //These are the default values, usually you don't need to set/change them
        UseHttps = true,
        EndpointSuffix = "core.windows.net"
    };
     
  • Added: CheckboxSelectionEnabled property for forcing “Item check boxes” mode regardless of being detected
    as a touch device.

  • Improved: Moved busy indicator from bottom status bar to breadcrumb navigation bar because
    some browsers like Chrome show status tooltip on bottom left corner and hide the UI.

  • Fixed: When there were many video files in a folder, occasionally (on app start) the thumbnails would not
    be loaded (infinite loading indicator). This happened due to a race condition in VideoThumbnailer.

  • Improved: Updated Media Player.

  • Fixed: When you referenced GleamTech DLLs and you populated all types in AppDomain like this:

    var allTypes = AppDomain.CurrentDomain.GetAssemblies()
        .SelectMany(a => a.GetTypes())
        .Where(t => t.IsPublic);

    You would receive this error:

    Method 'Clone' in type '_hB' from assembly 'Licensing, Version=1.3.0.0, Culture=neutral, PublicKeyToken=a6f3cafa178e6038' does not have an implementation.

    Licensing.dll is fixed to prevent this error.

Version 5.10.0 - June 20, 2017

  • Added: New “Item check boxes” mode for convenient multiple selection of files/folder especially on touch devices. The option can be toggled on “View” tab of ribbon. For tablet and phone devices this option will be turned on by default because drag-selecting is hard (long press and scroll) on these devices (unlike desktop where mouse is available). So check-selecting is better for these devices. Check-selecting works with all (6) view layouts.

  • Fixed: Thumbnails were not loading on iOS (retina).

Version 5.9.12 - June 15, 2017

  • Fixed: DocumentViewer failed to open DCM (dicom image) files.

Version 5.9.11 - June 13, 2017

  • Fixed: When ASP.NET impersonation was used via <identity impersonate=“true” … /> tag in web.config, when accessing temporary folder impersonation was being reverted “just in case”. This will not be done anymore because it cause access errors in some cases.

    More info about ASP.NET impersonation:
    Actually the user in <identity> tag already has to have permissions on “Temporary ASP.NET Files” because ASP.NET runtime throws an error on startup so we can assume the user can already access if the application is running.

    <identity impersonate=“true” /> (no user) impersonates IUSR when Anonymous Authentication is used and suprisingly IUSR is not member of IIS_IUSRS, only app pool identities are (via automatic injection). When Windows Authentication is used, this will be the logon user. So you are responsible for adding any impersonated user including IUSR to IIS_IUSRS group to grant “Temporary ASP.NET Files” access.

    After adding IUSR to IIS_IUSRS group, you need to run “iisreset” in Administrator Command Prompt. This is because changes to user’s group membership are not effective until the next time the user logs on.

    If you are running the app pool as a domain user, the rules change on the automatic injection of IIS_IUSRS token into the process at startup. Solution: Create a new active directory user group named “IIS_IUSERS” in Users OU. Then join your iis users to this group. After that, adding that user group to local IIS_IUSRS group solves your problem.

  • Improved: Document Viewer:

    • Improved: Got rid of HTTP headers used in DocumentViewer when downloading the XPZ. Parameters will instead passed via regular querystring. This will probably fix some random “Invalid XPZ file” errors.

Version 5.9.9 - June 8, 2017

  • Fixed: When using a root folder with impersonation, Document Viewer and Video Player failed to open files.
    Image Viewer was opening the files.

Version 5.9.8 - June 6, 2017

  • Fixed: Still happening issue, completely fixed now: When a license key was set and debugging in
    Visual Studio on Windows 10 Creators Update, the opened browser hanged on forever. The issue only happened
    on .NET 4.7 framework which came with Windows 10 Creators Update.

Version 5.9.7 - June 3, 2017

  • Improved: ImageCache and DocumentCache locking, prevented double entries for same uniqueId with
    different file name if requested at the same time.

Version 5.9.6 - May 29, 2017

  • Fixed: When a license key was set and debugging in Visual Studio on Windows 10 Creators Update,
    the opened browser hanged on forever. The issue only happened on .NET 4.7 framework which came with
    Windows 10 Creators Update.

  • Improved: Document Viewer:

    • Fixed: Viewing TIFF files was broken with this error:
      Object reference not set to an instance of an object.

    • Fixed: When viewing image formats, the generated PDF files in cache folder were kept open
      (could not be deleted).

Version 5.9.5 - May 25, 2017

  • Fixed: Thumbnails sometimes appeared blank in FileManager especially in Chrome.
    Also improved lazy loading of thumbnails with better “in viewport” detection.
    Also fixed CTRL+F5 (or “disable cache” in developer tools) causing broken images issue.

  • Fixed: Search box label was not changing when changing folders and it was always displaying
    the name of first root folder, although the search was done in the correct folder.

  • Fixed: Actions “Add to zip” and “Extract” could fail when dealing with zip files due to timeout.
    Also fixed zip generation for some files of certain size (exact divisible of 64k).

  • Improved: Date column will be empty for folders with default/min date (e.g. 01/01/0001),
    this is especially useful for AmazonS3 and Archive folders which usually does not have a valid/useful date.

  • Improved: Upload window: “Select files to be uploaded” label was truncated on high DPI.
    Added Remove and Clear buttons for better touch support (alternative to context menu), removed Close button.

  • Improved: Updated Media Player.

  • Improved: Document Viewer:

    • Fixed: Errors before “please wait a moment” dialog was not displayed. Also downloading indicator animation
      (blue rectangle) was not displaying (the one after “please wait a moment” dialog).

    • Improved: Conversion accuracy for WordProcessing, Spreadsheet, Diagram formats.

  • Fixed: License domain check for 3 letter domains failed as they were mistakenly treated as TLDs.
    Possible “Request is not available in this context” on probably earlier .net 4.0 versions when license key is set.

Version 5.9.3 - May 4, 2017

  • Improved: Document Viewer:

    • Improved: Conversion accuracy for Cad formats.

    • Added: Grayscale printing. The print dialog in DocumentViewer now has a “Grayscale (Black and White)” option.

Version 5.9.2 - May 2, 2017

  • Fixed: Clicking on UI items was not working on Firefox 52+ when used on a touch-enabled device.
    Firefox changed a default browser behavior/setting in recent versions which broke clicking behavior
    in some products: If you have a touch enabled laptop or PC monitor and when you use a mouse,
    your clicks were not received by the controls displayed in Firefox. The problem did not happen if you
    did not use a touch-enabled device.

  • Improved: Document Viewer:

    • Fixed: Sometimes DocumentViewer’s vertical scrollbar’s bottom button was not visible.

    • Fixed: Especially on IE, DocumentViewer’s pan tool (hand cursor) was overlapping scrollbar so it made the user
      think the hotspot was on the scrollbar but when the user moved the mouse the user was actually still panning the
      document because the hotspot of the hand cursor was still on the document and not on the scrollbar.
      This confused the user thinking into clicking on scrollbar caused “jumping back to the first page of the document”.
      Now, when the user approaches a scrollbar, the hand cursor will be changed to default cursor and panning too near
      the scrollbar will be disabled. This way panning and scrolling actions will never be confused.

    • Fixed: When printing on IE, an extra blank page was being added at the end.

    • Improved: Viewing accuracy for Presentation and Imaging formats.

Version 5.9.0 - April 24, 2017

  • Changed: Licensing model. From now on, the license types are Professional, Enterprise, Distribution and Source. Your existing license type (Developer, Developer OEM, Site, Site OEM) will still be valid but license keys are changed so please go to https://www.gleamtech.com/upgrade and acquire a new license key if you want to use this version (or higher). If your one year maintenance has not ended, you will receive a new license key without a charge. After your maintenance has ended, you will be able to upgrade to only new license types.

  • Fixed: DocumentViewer was not displayed in IE11 with “Please use an HTML5 Compatible browser” error when IE Enterprise Mode was active. This is because Enterprise Mode emulates IE8 and DocumentViewer supports IE9+. Now DocumentViewer will force latest IE mode and will display as expected even in Enterprise Mode.

  • Improved: Real version will be shown in “Description” field of Visual Studio reference property window. This is the FileVersion of the DLL, Visual Studio by design shows AssemblyVersion in “Version” field of that window which confused some developers. AssemblyVersion is changed only when there is a breaking API change which requires a recompile so it’s not changed often, however FileVersion is changed for every release. This way, the developer can make sure exactly which DLL version is referenced from within Visual Studio (no need to go to Windows Explorer
    and check file properties).

  • Fixed: Setting FileUltimateConfiguration.Current.TrialExtensionKey did not have effect immediately, it was delayed for about 20 minutes.

Version 5.8.2 - April 7, 2017

  • Improved: High quality printing in DocumentViewer. The print dialog in DocumentViewer now has a “High Quality” option which is enabled by default. Printing in high quality will prevent pixelation of text.

Version 5.8.1 - April 4, 2017

  • Improved: Stability of DocumentViewer UI. Added back and forward navigation buttons to the toolbar.
    Error messages in the modal dialog can now be selected for copy/paste.

  • Fixed: The soft error which may be logged in server logs:
    ‘GleamTech.DocumentUltimate.Resources.webviewer.Html5.external.images.ui-bg_glass_95_fef1ec_1x400.png’ not found in assembly ‘GleamTech.DocumentUltimate …’

Version 5.8.0 - March 25, 2017

  • Improved: Document Viewer:

    • Re-enabled email formats (.msg).

    • Fixed pre-filled form fields of PDF files not displaying issue.

  • Fixed: Drag & drop issue within FileManager. Thumbnail image was dragged when mouse moved (browser’s internal d&d), where the whole item should be dragged. Probably was broken since 5.7.0.

  • Fixed: Navigation breadcrumb bar arrows were not working (losing clicks) when FileManager was added to a page with a margin.

  • Improved: Internalized some libraries like Newtonsoft.Json to prevent assembly conflict warnings in Visual Studio.

  • Improved: Updated Media Player.

Version 5.7.4 - February 13, 2017

  • Fixed: Bookmarks (Outlines) for PDFs were lost/missing in DocumentViewer.

  • Added: New document formats for Document Viewer:

    • .ots - OpenDocument Spreadsheet Template
    • .otp - OpenDocument Presentation Template
    • .dcm - Digital Imaging and Communications in Medicine (DICOM)
    • .webp - WebP Image
    • .djvu - Deja Vu (DjVu) Image
  • Added: File icons for extensions:

    • .ots
    • .otp
    • .jp2, .jpf, .jpx, .j2k, .j2c, .jpc (JPEG 2000)
    • .jxr, .wdp,. hdp (JPEG XR)
    • .dcm (DICOM Image)
    • .djvu (DjVu Image)
    • .wmf, .emf, .dib

Version 5.7.0 - January 11, 2017

  • Improved: Document Viewer. Added JPEG XR (HD Photo) (.jxr, .wdp, .hdp) format support. Disabled browser’s right-click context menu for thumbnails in Document Viewer so that saving thumbnails is prevented.

  • Fixed: When FIPS was enabled on the machine, you could see evaluation watermark in documents opened by Document Viewer.

  • Improved: Updated Media Player.

  • Improved: Pinch and double-tap gestures (zoom in and out) on mobile devices.

Version 5.6.4 - January 3, 2017

  • Fixed: Still in some cases, "Could not load file or assembly" errors (yellow screen of death) when the web app first starts.

Version 5.6.2 - December 5, 2016

  • Improved: Stability of Document Viewer.

  • Improved: Updated example projects Mvc.CS and Mvc.VB from ASP.NET MVC 3 to ASP.NET MVC 4 so that they can be properly edited (no Razor warnings) in Visual Studio 2015 while keeping compatibility back to Visual Studio 2010. Also added ASP.NET MVC 4 as Nuget references so that it can be restored automatically when project is ran in Visual Studio.

Version 5.6.1 - November 26, 2016

  • Improved: Merging of DLLs. We are now using an in-house built assembly merger and resolver. The new resolver is more performant (you should notice faster startup times), reduces the memory footprint, handles error better and provides detailed logging in the temporary folder and also in VS Debug Program Output Window when attached. Also the size of the product DLL files are slightly reduced due to better compression. We will offer this new assembly merger and resolver as a new product soon.

Version 5.6.0 - October 26, 2016

  • Improved: Document Viewer. Full CAD support. DWG files (AutoCAD R13, R14, 2000, 2004, 2007, 2010, 2013, 2016) and DXF files (AutoCAD R12, R13, R14, 2000, 2004, 2007, 2010, 2013, 2016) can now be opened with DocumentViewer. In previous versions, there was DWG and DXF support but it was pretty limited and it could only load very few AutoCAD format versions. Now any AutoCAD file you throw at it will work.

Version 5.5.6 - October 22, 2016

  • Fixed: Possible wrong “evaluation has expired” error in Document Viewer.

Version 5.5.5 - October 17, 2016

  • Added: Visual Studio Design View support. From now on, an image preview (placeholder) of FileManager control will be displayed in Design View. This preview is also resizable and it directly reflects Width and Height properties.

  • Fixed: Visual Studio Design View error: “Cannot create an object of type ‘GleamTech.FileSystems.Location’ from its string representation…”

  • Fixed: Amazon S3 root folders can now list more than 1000 items. Also improved listing performance of folders so you should not have any problems with huge buckets.

  • Fixed: When Amazon S3 bucket was empty, it caused an error.

  • Fixed: ClientLoading event was being fired too late, some functions like fileManager.onViewRefresh are registered as event handlers to internal components so even you override them later the components still referred to the old function reference, so Ext.override was not working. From now on ClientLoading will now fire at the start of initComponent and ClientLoaded at the end of initComponent. ClientLoading should be used for Ext.override calls, ClientLoaded should be called for adding actions, UI elements.

  • Fixed: IE11 on touch laptops were detected as a mobile device so Document Viewer was displayed in mobile mode. Improved mobile device detection to prevent this kind of issues.

  • Improved: Document Viewer. Some formats (e.g. common image formats and digital paper formats like XPS and EPUB) will be opened faster for first-time view. More formats can be viewed with Document Viewer.

  • Improved: Updated Media Player. Also updated the skin to youtube style.

  • Improved: Image and document caches will now group cached files for the same inputs in subfolders. Also the subfolder name will contain the original file name so it will be easier to locate the corresponding cached files for an input. The old cached files will be arranged into the new structure automatically one by one when they are accessed so no action is required for the developer.

Version 5.5.0 - September 13, 2016

  • Added: Thumbnails and Image Viewer will be available for the common raw file (camera format) extensions:

    • dng (Adobe)

    • arw, srf, sr2 (Sony)

    • cr2 (Canon)

    • nef, nrw (Nikon)

    • raf (Fuji)

    • orf (Olympus)

    • pef (Pentax)

    • kdc, dcr (Kodak)

    • mrw (Minolta)

    • erf (Epson)

    • rw2 (Panasonic)

    • dng (Leica)

    • srw (Samsung)

    • x3f (Sigma)

  • Added: EPS format support (if TIFF preview image exists inside it) for thumbnails and Image Viewer.

  • Improved: When a thumbnail generation fails for an image or a video file, an image of the file extension icon with a red error sign on the bottom right corner will be displayed. Thumbnail generation can fail when a file is corrupted or has some invalid format, for example some EPS files can not be opened if there is no TIFF preview image inside it. The special error image will be also cached so you will not see unnecessary errors related to thumbnail generation when you browse a folder with corrupted files every time. Also when clicked “Preview” on a corrupted image, Image Viewer will show a 256x256 size of this special error image.

  • Improved: Thumbnails will be generated vastly faster. EXIF thumbnails will be loaded and resized if possible. Also usual resize (Thumbnails or Image Viewer) will be faster for Jpeg files as downscaling will be used while reading them when possible.

  • Improved: Document Viewer. Updated document conversion engine, conversions will be faster and support for some file types like Microsoft Project (.mpp) are improved (chance of failing to load some files is reduced). Cache will not keep the file if conversion is failed before viewing the document. This will prevent possible ghost zero-size files. This way only successful results will be cached. This should prevent possible “Invalid XPZ file” errors.

  • Improved: Updated Media Player.

Version 5.4.0 - August 9, 2016

  • Fixed: Dynamic feature detection was broken. When GleamTech.DocumentUltimate.dll, GleamTech.ImageUltimate.dll or GleamTech.VideoUltimate.dll was not included in bin folder, this caused a runtime error. Now these files can be excluded safely again to opt-out from the corresponding features as expected.

  • Added: PSB (Photoshop Large Document Format) format support for thumbnails and image viewer.

  • Added: File icon for PSB extension.

  • Improved: Document Viewer.

Version 5.3.8 - May 22, 2016

  • Added: ImageViewerEnabled, MediaPlayerEnabled, DocumentViewerEnabled, ArchiveBrowsingEnabled properties so that you can disable the corresponding features if required. Also moved ImageThumbnailsEnabled and VideoThumbnailsEnabled properties from FileUltimateConfiguration to FileManager class so that they can be disabled on instance-level and not for whole application.

  • Improved: When access is denied to the cache path, a more user-friendly error message with instructions will be displayed. Also the physical path will not be included in the message for security purpose.

  • Improved: Updated GleamTech.Core for allowing access via IP for domain restricted licenses.

  • Fixed: In Web Site projects, when you added FileManager markup in an aspx page and built the web site, the build failed with the following error message (actually 3 error messages but main one is this, others are consequences): Cannot create an object of type 'GleamTech.FileSystems.Location' from its string representation.

  • Fixed: When FileManager was inserted in a page with AngularJS, clicking on context menu items did not work and instead caused a redirect to the home page. This was because AngularJS took over all <a href="#"> links on the page and as AngularJS considered them as a navigation and as there's no route specified it redirected to the home page. To be compatible with AngularJS, from now on menu items will use <a href="javascript:"> as links.

  • Fixed: When in details view, clicking on "Type" column did not sort the files.

  • Fixed: Unnecessary "Path cannot be discovered" error when a root folder had no permissions.

Version 5.3.6 - May 16, 2016

  • Fixed: Moving a folder which had files at second and higher level depth failed.

  • Fixed: FileManagerRootFolder.GetFolder was broken when the root folder had no access control.

  • Added: TotalSize, ElapsedTime and TransferRate properties to FileManagerDownloadedEventArgs so that more information will be available in Downloaded event.

  • Improved: Updated media player, document conversion, graphics and video engines.

Version 5.3.5 - May 11, 2016

  • Fixed: Some problems continued on Internet Explorer and Microsoft Edge browsers after the new drag and drop feature. For example, columns on the file list were not clickable anymore. With this version all problems related to clicking should be fixed and clicking should feel more responsive again.

  • Fixed: Some UI quirks. For example error window was still displaying behind the background mask on some cases and minimize/restore state of a window was not stable (scrolling the main view behind the window caused it the window to minimize).

  • Improved: Made the default action of dragged items "Move to" even if the drag is made across view (eg. dragging from main view to folder tree). So "Copy to" action will be switched on only if CTRL key is pressed. This exactly mimics "Windows Explorer" behaviour.

  • Fixed: After you drag and drop in the folder tree, you could get an error message when you clicked the parent folder. When dragging, the tree was confused and changed the current selection to the dragged one (focused) although this was not visually reflected so we had a ghost selection.

  • Fixed: Prevented horizontal scroll of folder tree when dragging on the right edge and waiting for 500ms. The scroll helper should only work vertically for the folder tree.

  • Fixed: While dragging on the bottom of the main view or folder tree, the page would flicker.

  • Improved: Updated PDF icon with the most recent one. Also fixed large icons for ascx, ashx, asmx, aspx, config, css, htm, js, resx, xsd, xsl, xml, h extensions so they will not be pixelated (not upsized from small icon).

  • Fixed: Icons for 1 letter extensions were not shown (eg. .c and .h), also "Type" column showed "File" instead of e.g. "C File".

  • Added: Wildcard support for FileManagerAccessControl.Path property. Now you can use these wildcards in a path: The ? wildcard character matches a single character. The * wildcard character matches zero or more characters. The ** wildcard character sequence matches a partial path. For example, if you set Path="\**\*MatchMe*", this access control will appy to the folders containing MatchMe keyword in name under both root folder and under root folder's all subfolders (recursive).

Version 5.3.1 - May 9, 2016

  • Fixed: Clicking and selecting folders was broken due to new drag and drop feature on Internet Explorer and Microsoft Edge browsers. Other browsers like Chrome and Firefox did not have this problem.

  • Fixed: Thumbnail images were being dragged instead of the item on Internet Explorer and Microsoft Edge browsers.

Version 5.3.0 - May 9, 2016

  • Added: Drag and drop feature with "Copy to" and "Move to" actions. Drag and drop works just like "Windows Explorer" both visually and functionality-wise including the modifier keys, i.e. during dragging pressing CTRL key will force "Copy to", pressing SHIFT key will force "Move to" and pressing ESC key will cancel the drag.

  • Fixed: "Paste" action was not displayed when right clicked on a folder on the right side (main view not the folder tree on the left)

  • Fixed: Close icon of a child window required multiple clicks on some occasions to close the window.

  • Fixed: In the folder tree, when pasted into a collapsed folder, it was not expanded although it's icon showed as expanded state (down arrow)

  • Fixed: When an error window was displayed, occasionally it was displayed behind the background mask, so it was not possible to close the window unless you pressed ESC key.

Version 5.2.0 - April 24, 2016

  • Added: Support for ASP.NET Web Pages projects, now you can use @Html.RenderCss, @Html.RenderJs and @Html.RenderControl just like ASP.NET MVC after you add @using GleamTech.Web.WebPages in your page.

  • Added: GleamTechWeb:ResourceOverridePath setting to override default resource location App_GlobalResources, for example App_GlobalResources is not allowed for precompiled web sites so another folder can be used in that case.

  • Added: Configuration can now be loaded from or saved to xml or json files.

  • Improved: Updated german language file.

  • Improved: Document Viewer.

Version 5.1.6 - April 11, 2016

  • Added: TGA (TARGA) format support for thumbnails and Image Viewer.

  • Improved: In Document Viewer, when session expires, a "Refresh page" dialog will be shown with a countdown of 10 seconds. Also server side errors while loading the document will be handled better and more detailed error messages will be displayed instead of a generic message.

Version 5.1.5 - April 4, 2016

  • Added: "Print" permission for controlling print, download as pdf and text selection actions in the document viewer.

  • Changed: Removed DisablePreviewerPrinting and DisablePreviewerTextSelection properties as these will now be controlled by the new Print permission per folder-basis.

  • Improved: The Document Viewer;

    • Added: "Download" and "Download as PDF" buttons to the toolbar. "Download" button will be disabled when there is no Download permission and "Download as PDF" button will be disabled when there is no Print permission. This is because, downloading a DOCX file as a PDF file is considered same as printing that document.

    • Improved: The toolbar is now reponsive, buttons will not be hidden and they will flow naturally to next row below. So all the available buttons will be visible regardless of the viewer size. Also the buttons are spaced better.

    • Fixed: Some scanned documents were displayed as blurred, i.e. the text was unreadable.

    • Fixed: Some XPS files were not being displayed at all.

    • Fixed: Even when the printing was disabled, the user could still open "Print Dialog" by pressing CTRL + P.

     

  • Added: New examples engine with flat/modern theme.

Version 5.1.0 - March 24, 2016

  • Added: New redesigned Document Viewer with same features.

Version 5.0.9 - March 13, 2016

  • Fixed: Updated GleamTech.Core for fixing license domain issue, i.e. www prefix should be considered same as the parent (e.g. contoso.com and www.contoso.com should be treated the same).

  • Fixed: Unable to upload or download a file with name containing &# character sequence.

Version 5.0.8 - February 7, 2016

  • Improved: Updated media player, document conversion, graphics and video engines.

Version 5.0.7 - January 27, 2016

  • Fixed: A security vulnerability with resource.ashx when application pool account was misconfigured.

  • Fixed: When no root folders were defined, the control was not being rendered due to a JS error (blank page).

Version 5.0.6 - January 24, 2016

  • Improved: Updated media player for better Firefox compatibility.

Version 5.0.5 - January 17, 2016

  • Fixed: Updated GleamTech.Core for fixing some routing issues.

  • Fixed: Image Viewer file types were not being considered as preview types so "Preview" command was not being shown/enabled in context menu and toolbar. However double-clicking on the file was still opening the Image Viewer.

  • Fixed: Text of buttons on toolbar had underlines when hovered in some pages if there was a:hover definition in page's CSS.

  • Fixed: .mhtml file extension icon was not shown like .mht.

Version 5.0.4 - January 11, 2016

  • Fixed: Intermittent "Could not load document" error in Document Viewer although the document was loaded and displayed.

  • Fixed: Media Player was not starting to play a video if it was in an archive (eg. zip file)

  • Fixed: For video thumbnails, the duration overlay text was not aligned exactly at center of the rectangle.

Version 5.0.3 - January 10, 2016

  • Fixed: Updated GleamTech.Core for fixing some possible Json serialization problems.

  • Fixed: Image Viewer did not refresh an image if it was edited externally, last modified time was not taken into account so the old version from the browser cache was displayed.

Version 5.0.2 - January 7, 2016

  • Changed: Slight licensing change to support new license types.

Version 5.0.1 - January 6, 2016

  • Fixed: "Could not load file or assembly Microsoft.Web.Infrastructure" error on some machines.

Version 5.0 - January 5, 2016

  • Added: New Windows 10 UI theme.

  • Added: New flat/modern file type icons.

  • Added: New advanced Document Viewer with High Resolution. Text, fonts and vector elements are preserved and rendered in high-res with no rasterization. Zoom in as much as you want, your document will look great. Also performance in regards to the old viewer will be much better.

  • Added: Advanced Image Viewer with zooming and panning feature. The viewer can display several image formats including Photoshop files.

  • Improved: New faster image thumbnail generation with caching support.

  • Changed: Some API. Renamed ControlContext to FileUltimateConfiguration, use FileUltimateConfiguration.Current to change global configuration. Removed FileManager.LicenseKey property, use FileUltimateConfiguration.Current.LicenseKey instead. Routes can be re-added via FileUltimateConfiguration.RestoreRoutes.

  • Changed: Separated GleamTech.FileUltimate.dll into multiple assemblies as some features are now also separate products. You only need to reference GleamTech.Core.dll and GleamTech.FileUltimate.dll in your project, the other DLLs in the same folder GleamTech.ImageUltimate.dll, GleamTech.VideoUltimate.dll and GleamTech.DocumentUltimate.dll are assemblies for the new products with the same name and also FileUltimate depends on them for some of the features. Msbuild or Visual Studio will automatically copy these 3 DLLs along with the main file GleamTech.FileUltimate.dll to your bin folder during build so they don't need to be referenced directly. Note that even without these 3 DLLs, FileUltimate will work but it will just turn off the corresponding features such as generating image or video thumbnails or the document viewer. So with this new modular approach, you can opt-out of the features you do not need by excluding one of the DLLs.

  • Improved: Many minor fixes and performance improvements.

Version 4.8 - October 13, 2015

  • Added: New advanced video thumbnail generation which is vastly faster and more stable than the previous feature. No more unexpected crashes due to bxsdk32.dll or ffmpeg.exe on some machines. We developed a library to directly access video files so there will be no more side effects of launching an external command line exe from IIS. The setting "FileUltimate:DisableVideoThumbnails" in web.config still works but as we solved the stability problems, you should not need to disable thumbnails for video files anymore. We may offer this high-performance and stable video frame reading library as a separate product soon.

  • Improved: The picture quality of the generated video thumbnails, you will notice that the duration text on the bottom right is now more crisp and readable.

Version 4.7.4 - October 5, 2015

  • Improved: Some minor issues are fixed and improvements are made.

Version 4.7.3 - September 24, 2015

  • Added: The public method ControlContext.RegisterRoutes for being able to re-insert FileUltimate related routes in case you clear the routes via RouteTable.Routes.Clear() at some point in your application.

  • Improved: The way some native DLLs are loaded so the below problem which still happens on some rare machines may be fixed:
        
        Intermittent w3wp.exe crashes related to bxsdk32.dll or bxsdk64.dll, in Windows Event Viewer an error similar to below was being logged:

     
        Faulting application name: w3wp.exe, version: 8.0.9200.16384, time stamp: 0x5010885f
        Faulting module name: bxsdk32.dll, version: 3.3.5.24, time stamp: 0x55803b90
        Exception code: 0xc0000005
      
      Note that if you still get this error after this version, you can use this undocumented setting in your web.config:
     
          <configuration>
            <appSettings>
              <add key="FileUltimate:DisableVideoThumbnails" value="1" />
            </appSettings>
          </configuration>
     
      This setting will disable generating thumbnails for video files only (image files are not effected) so that you can avoid this error altogether by sacrificing only the related feature.

     

Version 4.7.1 - July 19, 2015

  • Improved: Ribbon (top) bar will now show left and right scrollers when there is not enough space (overflow) so that all buttons are accessible regardless of the window size.

Version 4.7 - July 6, 2015

  • Added: Amazon S3 file system. You can now use an Amazon S3 bucket like a regular folder on disk.

  • Improved: FileManagerRootFolder.Location property is now of type Location class instead of string. You can still assign a string to this property as it's automatically casted so this is not a breaking change. The advantage of this special Location class is that you can now set it directly to an instance of PhysicalLocation or AmazonS3Location (more will be available in the future) classes. For instance this line:
     

        rootFolder.Location = "Type=AmazonS3; Bucket Name=mybucket";

      is same as this line:

        rootFolder.Location = new AmazonS3Location { BucketName = "mybucket" };

      This means you don't need to bother with formatting location strings correctly (eg. guessing property names) Except in aspx markup, you will still need to use strings which look like connection strings if you need to set advanced properties. Also note that this line:

          rootFolder.Location = "c:\some\folder";

      is same as this line:

        rootFolder.Location = "Type=Physical; Path=c:\some\folder";

      and also same as this line:

        rootFolder.Location = new PhysicalLocation { Path = "c:\some\folder" };

      So as in previous versions, setting location to a path string directly means it's a physical location by default.
     

     

Version 4.6.6 - June 26, 2015

  • Fixed: Open/Download actions failed with file names containing % and & characters. This is because since v4.6.1, paths/file names were being included directly in URL and IIS and ASP.NET by default disallows certain characters in a URL, so made sure all of these characters are handled specially.

  • Fixed: FIPS compliance (error about MD5 algorithm) was broken due to how DLL was being built since 4.5.2.

  • Improved: When opening a file (not previewing), if the browser did not recognize this file type (ie. it has no default viewer for it), it would show open/save file dialog as expected. However as a side-effect, a blank window was being left open. This window is normally used by browser to display supported file types inline/embedded. However there was no reliable way to detect if the browser actually displayed the file via its plugins or showed open/save dialog, thus we were leaving the window open. Finally we developed a workaround to detect this in a cross-browser way. From now on, if the window is blank, it will be closed automatically.

  • Improved: Document Viewer will now be localized (tooltips for top toolbar buttons etc.) according to the current display language.

Version 4.6.5 - June 19, 2015

  • Improved: From now on slash (/), backslash (\) and colon (:) characters can be used in root folder name. Paths will now be represented with square brackets around root folder name eg. [RootFolderName]:\Some\Folder (in previous versions it was like RootFolderName:\Some\Folder). This way previously illegal characters will be escaped safely. Now only limitation is that the name can not contain the character sequence "]:" (right square bracket preceding colon) which is very unlikely.

  • Changed: Excluded html, xml and txt file extensions for preview as it makes more sense to open them directly with browser (document viewer is not very useful for these file types). Considering referenced resources (eg. images) for html pages can be loaded since v4.6.1, it's better to make "Open" action default for best display of these files.

Version 4.6.4 - June 16, 2015

  • Improved: More accurate impersonation according to the folder being local or network. By detecting if the folder is local or network, best logon type will be selected to make sure impersonation succeeds. This will especially fix problems when connecting to permission-protected local folders via non-local/domain users.

  • Fixed: "Authenticated User=true" setting for location was not working as expected. This setting allows to impersonate the user already authenticated via IIS Windows Authentication mode.

  • Fixed: When impersonating a user while accessing a local folder, if this user did not have NTFS Modify permission on App_Data folder, "access denied" error occured. The error occured either if logging events to database failed or caching by document viewer (preview) failed due to not being able to write in App_Data folder. From now on, impersonation will be reverted (back to AppPool identity) at the correct time so you won't need to give Modify permission for your users on App_Data folder.

  • Improved: For "Open" and "Preview" actions, if the file is already open in a window, then that existing window will be brought to the front instead of creating a new window every time for the same file.

  • Added: "ExcludedExtensionsForPreview" property. This can be set to comma-separated file extensions. "Preview" action for these file extensions will be disabled.

Version 4.6.2.2 - June 10, 2015

  • Fixed: CreatePublicLink permission was represented with wrong value in UI. It was bound to Paste permission.

  • Fixed: Expanding the collapsed NavigationPane caused a JS error. On IE11, the pane was not even expanding due to error.

  • Fixed: When text selection was disabled, "File not found" error occured for DXF files on Document Viewer.

Version 4.6.2 - June 9, 2015

  • Added: "DisablePreviewerPrinting" and "DisablePreviewerTextSelection" properties. You can now disable printing of files displayed in Document Viewer and disable text selection (ie. copying via CTRL + C) on the Document Viewer for further protection of your files.

Version 4.6.1 - June 5, 2015

  • Added: "Open" action now can display HTML pages correctly which has relative resource links (images, CSS, JS). All linked resources (eg. <img alt="" src="../images/some.jpg" />) will be resolved so HTML page will be rendered perfectly (no broken images or styles). This mimics the behaviour when you open a local HTML file in Windows Explorer.

  • Fixed: When using Microsoft Forefront UAG (reverse proxy), the built-in Document Viewer was not displaying document pages (blank pages). It was working when accessed via localhost but not when accessed via external URL.

Version 4.6 - June 1, 2015

  • Added: Advanced Document Viewer which can open and display (read-only) wide range of document and image file formats:

    • Portable Document Format: pdf

    • Microsoft Word: doc, docx, docm, dot, dotx, dotm

    • Microsoft Excel: xls, xlsx, xlsm, xlsb

    • Microsoft PowerPoint: ppt, pptx, pps, ppsx

    • Microsoft Visio: vsd, vdx, vss, vsx, vst, vtx, vsdx, vdw

    • Microsoft Project: mpp, mpt

    • Microsoft Outlook: msg, eml, emlx

    • OpenDocument Formats: odt, ott, ods, odp

    • Rich Text Format: rtf

    • Plain Text File: txt

    • Comma-Separated Values: csv

    • HyperText Markup Language: html, mht, mhtml

    • Extensible Markup Language: xml

    • XML Paper Specification: xps

    • AutoCAD Drawing File Format: dxf, dwg (2004)

    • Image files: bmp, gif, jpg, png, tiff, multi-page tiff

    • Electronic publication: epub

    • Windows Icon: ico

    From now on, your users don't need to have an application (eg. Microsoft Office) on their computer to be able to view these documents.

     

  • Added: "Preview" permission to differentiate "opening files with built-in viewers (Document Viewer and Media Player)" from "downloading and opening files locally (or opening inline in browser)". Now you can allow your users to only preview files but not download them when required. This can be useful for copyrighted/protected documents, images, videos and audios.

  • Added: "Preview" action (next to "Open" action) to the ribbon and file context menu.

  • Added: "Previewing" and "Previewed" events.

  • Added: "DownloadOnDoubleClick" property. From now on, when you double-click on a file, "Preview" action will be triggered. If "Preview" permission is not allowed or the file type is not previewable by any of the built-in viewers, then "Open" (open inline in browser or open locally) action will be triggered. If you wish to use the same behaviour as in previous versions, ie. trigger "Download" action on double click then you can set "DownloadOnDoubleClick" property to true.

Version 4.5.2.2 - May 27, 2015

  • Fixed: "Not a valid Win32 FileTime" error when extracting some zip files on some machines.

Version 4.5.2.1 - May 25, 2015

  • Fixed: Downloaded files were corrupted when you had Telerik RadCompression module in your application. This version automatically removes any possible filters from Response.Filter like Telerik RadCompression before sending the file (download). RadCompression has a bug, ie. it takes over the response and gzips (compresses) it even if the response is a binary file (not AJAX response) and then it fails while gzipping due to FileUltimate sending the file chunked (not buffered). As a result the downloaded file is corrupted, from now on FileUltimate will not be effected by misbehaviour of any external modules.

Version 4.5.2 - May 20, 2015

  • Changed: Dropped Medium Trust (Partial Trust) support so Full Trust is required from now on. Few years ago, Microsoft officially stated that they have provided guidance to hosters that they should migrate away from Medium Trust and use proper OS-level isolation instead (KB2698981) and most of the shared hosters are already using Full Trust. We needed to do this change to be able add advanced features in future versions as Medium Trust has some severe limitations. Note that before this version some features like generating thumbnails for video files already required Full Trust and they were disabled silently when running under Medium Trust. From now on, the DLL will fail to load with an error when Full Trust is not available (the DLL is built differently and it requires Full Trust to even load). Note that this change does not matter if you are using a dedicated hosting or if you have your own servers because by default ASP.NET is already installed with Full Trust on Windows Servers.

  • Improved: The way how the control is initialized on Application Start. If you are using an ASP.NET Web Site project instead of ASP.NET Web Application project to host the control, this should fix the possible "The given key was not present in the dictionary" error.

  • Changed: Reduced the DLL size by 2 MB. Note that this change is not permanent as in the next version we plan to add "Document Viewer" feature which will increase the DLL size vastly due to new dependencies. Current size reduction is mainly for saving some space for the next version. Also note that you should not worry about DLL size as it will not effect performance, actually loading one large DLL is usually faster than loading multiple small DLLs.

Version 4.5 - April 29, 2015

  • Added: Media Player which can open and play video files (mp4, m4v, f4v, mov, flv, webm, ogv and on some browsers mp4v, 3g2, 3gp, mkv) and audio files (mp3, aac, m4a, f4a, ogg, oga, vorbis). Media Player will first try Html5 video feature of the browser and if not supported it will try Flash mode. If a media format is not playable on the browser, media player will prompt the user to try opening the file directly.

  • Fixed: When opening a video file of format like avi or wmv on IE, Windows Media Player was not able to play the file. From now on, Windows Media Player (or other players) will be able to stream the opened file without any problems.

  • Added: Assigned file icons and thumbnail generation to some additional media formats which the new Media Player supports.

  • Improved: When downloading a single file, resuming in the browser will be possible (again like older versions v3.x).

Version 4.4.5 - April 14, 2015

  • Added: Native ASP.NET MVC 3+ support. You can now render a FileManager in a MVC view by calling the 3 methods Html.RenderCss, Html.RenderJs and Html.RenderControl with an instance of FileManager class as the parameter. Updated examples to include MVC projects for C# and VB.

  • Added: 2 new properties ShowRibbon and CollapseRibbon. You can hide the ribbon (top pane) completely or show it in collapsed state. These properties are especially useful when using Chooser mode (updated chooser examples).

  • Improved: Some minor issues are fixed and improvements are made.

Version 4.4 - April 1, 2015

  • Added: ArchiveFileSystem which supports these archive formats: zip, 7z, rar, tar, gz, tar.gz (tgz), tar.bz2 (tbz, tbz2). From now on, the contents of these archive formats can be browsed just like regular folders. This is similar to "Compressed Folders" in Windows Explorer but for all archive formats not just for zip format. In addition, it supports displaying thumbnails while in archive and browsing nested archive files so it's more advanced than Windows Explorer's feature. The zip files can be modified but other formats are read-only as of current version. For example, you can directly upload into zip files or download files directly from all archive files. You can now use "Extract all to" or "Extract all here" actions for all archive types and not just for zip files. As archives are treated like regular folders, you can also use Copy/Cut/Paste actions to extract specific files and folders. When you browse a folder which contains archive files, these will be displayed like a folder (but with their specific archive icon) in the folder tree (navigation pane). Added better icons for all supported archive formats to be consistent with the original zip file icon.

  • Fixed: The browser was freezing when opening large folders (> 10,000 items) even in "Details" view layout.

  • Improved: When opening a folder with more than 1,000 items, the view layout will be automatically changed to "Details" as it's the fastest view layout (it renders only visible rows). Other view layouts will be also disabled as they will slow down the browser after 1,000 items and they will be actually useless for browsing that many items.

  • Fixed: On some servers, when pressed on upload button on the upload window, "Strong-named signed assemblies must specify a public key in their InternalsVisibleTo declarations" error was displayed.

  • Fixed: SortRootFolders property when set to false was not working as expected.

  • Improved: Some minor issues are fixed and improvements are made.

Version 4.3 - March 2, 2015

  • Added: Long path (upto 32,000 characters) support. Normally paths upto 260 characters were supported due to limitations of the .NET framework. From now on, it's possible to browse very long paths (very deep folders) and do any action in them without any error.

  • Added: Abstracted file system so adding new types of file systems will be easier. So managing files in a database or in a zip file will be possible. In next versions, we plan to first add support for zip files and other popular archive formats like rar, 7z, tar etc.

  • Improved: Path security. In previous versions, leaking underlying physical paths in error messages to the user was prevented for most cases. With this version, all cases are handled as file system is abstracted and isolated.

  • Improved: Quota handling. From now on, you can not break the limit in subfolders of a root folder with quota.

  • Improved: Finding copy name for existing files. For example, if "Image (2).jpg" exists "Image (3).jpg" will be created and not "Image (2) (2).jpg".

  • Improved: Upload speed for Html4 method vastly (12x-14x faster). Although Html4 method is not used too frequently as it is the last fallback method (Html5 -> Silverlight -> Flash -> Html4), this improvement will be useful for old browsers.

  • Added: New property InitialFolder which specifies the folder that should be selected and displayed initially. It should be set to the full path of the folder like "RootFolderName:\Some\Folder". If omitted, the first root folder will be selected automatically just like the default behaviour in previous versions.

  • Changed: Renamed MaxZipFileSize property to MaxSizeToCompress to imply its purpose better, ie. limiting maximum size to compress (per action). This property is usually used to prevent users creating large zip files (or other compressed archive files in future) which is CPU intensive. The name is changed as it will not be a zip-only setting in the future and also as it actually limits the total size of the input files rather than the final size of the generated zip file. 

  • Added: New property LimitDiskUsage to FileManagerAccessControl. This property is only useful when set to false to override the quota setting of the parent folder, ie. when you need unlimited disk space in a subfolder of a parent folder with limited disk space. When Quota property is set, LimitDiskUsage is set to true implicitly.

  • Improved: Many minor issues are fixed and improvements are made.

Version 4.2.2 -  January 23, 2015

  • Improved: From now on App_Data\Tools folder and contents (DLLs etc.) will not be created. This version will automatically delete this folder when first loaded. If it fails and you still see this folder, you can delete this folder completely. The DLLs will be generated in "Temporary ASP.NET Files" folder for the application instead so you will be able to publish your site without hitting any locked files.

  • Fixed: Intermittent crashes related to bxsdk32.dll or bxsdk64.dll "0xc0000005 - Access Violation" error were being logged in Windows Event Viewer when running on IIS.

Version 4.2.1.4 -  January 14, 2015

  • Fixed: On IE8, "Invalid source HTML for this operation" error is raised when downloading an item if FileManager control is inserted inside a form tag (eg. ASP.NET form).

  • Fixed: Intermittent crashes related to bxsdk32.dll "0xc0000005 - Access Violation" error when running on Visual Studio (especially 2010) or when running "ASP.NET Web Site Administration Tool".

Version 4.2.1 -  December 27, 2014

  • Fixed some UI issues:

    • On iOS, "Extract All" button on the ribbon was not showing its menu when clicked.

    • Replaced the ribbon pin icon with a better one.

    • On IE 8, disabled buttons and menu items had ugly text rendering (artifacts) and their icons were not semi-transparent as they were supposed to be.

    • Made hover color gray for disabled menu items.

    • On IE 8 and 9, context menus were not hidden when clicked on an empty area in the main view.

    • In details layout for main view, the "Name" column was not smoothly resizing when dragged.

     

Version 4.2 -  December 20, 2014

  • Added: Up button for navigating to parent folder easily.

  • Added: Breadcrumb navigation which allows users to keep track of their location and to drill down folders easily. 

  • Added: Refresh button for refreshing the current folder as an alternative to the context menu action.

  • Added: Search box for doing basic search in the current folder. This is the initial iteration for future support of more advanced recursive search.

  • Improved: Changed drag selection behavior to prepare for future drag & drop support. Selection rectangle will appear only when clicked on an empty area (not on icon, thumbnail or text). This mimics Windows Explorer behavior.

  • Improved: Prevented displaying "permission denied" message box when double-clicked on a file in a folder with no Download permission. Instead, double-click will be silently ignored.

  • Improved: Refresh behavior in navigation pane for cut and paste operation.

  • Fixed: Some minor UI glitches.

Version 4.1.5 -  November 11, 2014

  • Fixed: When using "Authenticated User=true" for root folder location, video thumbnails could not be generated (image thumbnails were fine) due to an impersonation issue.

  • Fixed: Prevented timeout errors for video thumbnail generation which was occuring when there were a lot of video files in the folder. This caused some files to not have a thumbnail (icon only).

  • Fixed: When an action was done (eg. renaming a folder) that caused the folder node in the navigation pane to refresh, the current folder selection was lost and the parent folder 2 levels up was being selected.

  • Improved: Reduced DLL size by 40% relative to previous v4.x versions.

Version 4.1 -  October 29, 2014

  • Added: Built-in impersonation support. RootFolder locations can be specified with user credentials.
    No more web.config settings are required to connect as a specific user or as the IIS authenticated user to a path.

    • For connecting as a specific user to a path (usually network paths), location should be specified with credentials in this format:
          Path=\\server\share; User Name=USERNAME; Password=PASSWORD
      Path can be UNC or local.User Name can be speficied as Domain\User, User@Domain (UPN format), MachineName\User or User (local user). If a value contains semi-colon character, that value should be enclosed in single quotes (eg. Password='PASSWORD') or double quotes (eg. Password="PASSWORD").

    • If IIS authentication is used for this site, location can be specified like this to connect as the already authenticated user:
          Path=\\server\share; Authenticated User=true

     

  • Improved: Control load time (especially when using UNC path and impersonation) at first page load.
    RootFolders will all show as expandable except if ListSubfolder permission is denied.
    No physical file system check will be done till page loads or user clicks expander icon.

  • Improved: Made error messages more clear when a folder is not accesible due to permissions or not actually exists.

  • Changed: Colon (:) character is no more allowed for root folder names.

  • Added: Resizable and ResizeHandles properties to allow user resize the control by dragging sides.

  • Added: DownloadWithChunkedTransferThreshold property which should be set only if you have problems downloading large files due to your environment limitations (reverse proxy etc.). For example, Microsoft Forefront UAG can not parse http reponses when content-length is larger than 2GB (throws HTTP 500 due to 32-bit integer limit) so it should be set to 2GB for UAG.

  • Fixed: When Width was set as percentage unit, the control was not being resized like v3.x when browser was resized.

  • Fixed: Prevented overriding host page's Body tag style like font-size.

  • Improved: Made all file types open in current window on iOS. Mobile safari is very restrictive with pop-ups and causes scrolling problems so it's better to open files in the same window to make sure native file viewers (images, PDF, DOC, XLS etc.) work properly.

  • Fixed: In some cases, lazy thumbnail loading was not initiated on browser resize causing some thumbnails to appear blank.

  • Fixed: Some vulnerabilities regarding paths (CVE-2014-8788 and CVE-2014-8789).

  • Added: ts and m2t extensions for video thumbnails.

  • Fixed: Too many Failed events were being raised when GetThumbnail action failed.

  • Added: On error message box, added a property tree for drilling down exception details easily.
    This is only useful for source code users as "details" section is only visible
    when the control is built with Debug configuration.

Version 4.0.9 -  October 11, 2014

  • Fixed: When pasted items copied or cut from another folder, current folder was not being refreshed.

  • Fixed: On touch devices, tooltip never disappeared and was not updated when a different item was selected.

  • Improved: Borders will be shown for focused but unselected items.

  • Minor UI improvements.

Version 4.0.8 - September 11, 2014

  • Fixed: In IE11, when downloading files with unicode characters in name, file names were corrupted.

  • Fixed: When manipulating RootFolders collection at codebehind, the index of a root folder was changed/reset when its Name property was changed. This caused subsequent access by index (eg. RootFolders[0]) to reference the wrong root folder.

Version 4.0.7 - June 30, 2014

  • Added: When the ribbon is unpinned, the ribbon will hide itself after clicking a command just like in Windows Explorer.

  • Fixed: In IE11, there was another blank page problem. This occured when "Display intranet sites in Compatibility View" option (Tools -> Compatibility View Settings) was checked. When this option is checked, IE11 renders the page in IE7 mode and FileUltimate does not support IE7 anymore starting with v4.0. From now on, FileUltimate will set "X-UA-Compatible" header to "IE=edge" for the host page so that IE11 is forced to render the page in Edge/Default mode.

Version 4.0.6 - June 1, 2014

  • Added: Swedish language.

  • Fixed: In IE11, when FileManager tag was placed inside a ASP.NET form, download and open actions stopped working due to a javascript error.

  • Fixed: Blank page problem on environments where the url is not allowed to contain parentheses. This caused the language file not to be loaded. One example environment is Microsoft UAG which did not have ( and ) as legal characters in URL by default so it rejected the language file request.

  • Fixed: When referencing FileUltimate in an ASP.NET MVC project, the Html.BeginForm method generated wrong url (resource.ashx) because of FileUltimate's own route table.

  • Fixed: In IE8, ribbon was displayed blank due to "tagName is null or undefined" error when some of the buttons were hidden due to permissions. This was not observable when the folder had full permissions.

  • Fixed: Text wrapping and sizing of ribbon buttons for non-english languages. Also made height of ribbon tabs consistent.

  • Fixed: When referenced a 3rd party library like Newtonsoft.Json.dll which is already bundled in GleamTech.FileUltimate.dll, class name conflicts occured.

  • Fixed: License key was not accepted with "Invalid license key" error when FIPSAlgorithmPolicy was enabled in Windows. This Windows setting is usually enabled by default especially for government agencies.

Version 4.0.5 - May 21, 2014

  • Fixed: In IE8 and IE9, folder was automatically selected/loaded when right clicked (context menu) in the navigation pane.

  • Fixed: On iOS, you could not touch and select a folder in the navigation pane.

  • Fixed: On iOS, drag-selector was not displayed properly (blue borders were separated from the center). Also improved the speed of drag-selector on other browsers.

  • Fixed: On iOS, sometimes image thumbnails were not loaded. This was due to touch scroll not being detected and thus lazy-image loading was not activated.

  • Added: On iOS, "Download" and "Open" commands did not work at all because of the popup blocker. Also In IE11, popup blocker was activated on "Open" command. To solve the popup blocker problems, added a new file viewer window. When you "Open" a file, a new browser window will not be opened anymore, instead the contents will be displayed in this custom window. If the file is an image, then it will be displayed nicely i.e. the image will be centered vertically and horizantally. Also on iOS, it is possible to touch scroll this image if it's bigger than the window. Note that you are still dependent on the browser for file types that can be displayed. If the browser can not open a file type, then it will prompt for open/download as usual.

Version 4.0 - May 16, 2014

  • Completely redesigned and rewrote the UI to resemble Windows 8 / Windows Server 2012 File Explorer

  • Added: A ribbon bar with large and small buttons for each command. Ribbon bar can be also collapsed.

  • Added: A new navigation (folders) pane which is collapsible and removable. In collapsed mode, when clicked on title, it can slide-in.

  • Added: A multi-view which supports 6 different view layouts:
      Extra large icons, Large icons, Medium icons, Small icons, Details and Tiles
    Details layout is similar to the grid in previous versions but has more features:
      Columns can be moved, resized and removed
      Ability to display thousands of items fast by only rendering items that are visible.
      When there are more than 1000 items in current folder, it's recommended to use this layout as it will not slow down the browser.
    Extra large icons, Large icons, Medium icons and Tiles layouts can display thumbnails.
      Thumbnails are lazy-loaded i.e. the image is requested from the server when the item is first visible so
      this improves performance when there are lots of images in the folder.
    Added a drag selector to allow easy selection of items which works in all view layouts.
    Added a new tooltip which displays detailed info when you hover on an item.
    Ability to switch between view layouts quickly any time via "Ribbon -> View tab" or via the status bar.

  • Added: New icons for every file type. 5 different sizes (256, 96, 48, 32 and 16) of each file icon is added so that they display perfectly in each view layout.

  • Added: Image thumbnails will be displayed for these file types:
      "bmp",
      "gif",
      "png",
      "jpg", "jpeg", "jpe", "jif", "jfif", "jfi", "exif",
      "tif", "tiff", "tff",
      "psd"
    Even on shared hosting (medium-trust), thumbnails can be generated for all types except psd (Photoshop file). Also on medium-trust, thumbnails will be generated for gif files but the quality of the thumbnails will be lower.

  • Added: Video thumbnails will be displayed for these file types:
      "avi",
      "mp4", "m4v", "mp4v", "3g2", "3gp",
       "mpg", "mpeg", "mpe", "vob",
      "mov",
      "mkv",
      "wmv", "asf",
      "m2ts", "mts",
      "flv"
    The duration of the video will also be added as an overlay at the bottom-right of video thumbnails (similar to YouTube). This is for giving quick information on how long the video is and also for being able to distinguish between video and image thumbnails at first sight.
    On shared hosting (medium-trust), video thumbnails cannot be generated.

  • Added: When a thumbnail cannot be generated for a file either due to hosting permissions or file corruption, then the icon for that file will displayed. Icons for all file types whether it is thumbnail-able or not are already provided.

  • Added: Commands in ribbon bar or context menus will be visible only when that folder allows the corresponding permission. In previous versions, a disallowed command was greyed-out but still visible. Hiding the disallowed commands completely will prevent the confusion of users and allow administrators to see what's allowed or disallowed at first sight.

  • Added: A status bar (bottom bar) which displays the number of items in current folder and number of selected items. When an action (request to server) takes longer time than a certain amount, the spinning busy animation will be also displayed here.

  • Added: Number formatting according to the current culture. In previous versions, dates were already formatted. Now numbers such as file size will also be formatted.

  • Added: Renamed Language property to DisplayLanguage and added new property FormatLanguage.
    DisplayLanguage property specifies the language of the user interface.
    FormatLanguage property specifies the language used for date and number formatting.

  • Added: New property ViewLayout which specifies the initial view layout type to display files and folders. The default value is LargeIcons.

Version 3.6.1 - May 21, 2013

  • Improved: Compatibility with iOS devices. It's now possible to scroll properly by touching and moving on white areas of folder tree and file listing. With iOS 6, it's now possible to upload files. Selecting multiple files to upload is also possible. Safari mobile renames all selected pictures to "image.jpg" so unique ids will be appended to file names to distinguish files.

Version 3.6 - May 14, 2013

  • Added: Completely redesigned the access control system. Different access controls can be specified for a root folder and its subfolders with FileManagerAccessControl class. Previously, this was possible to do in code (via FileManagerRootFolder.AddSubfolder method) but now it's also possible to do in markup and object model is improved and made consistent between code and markup. Permissions can now be set as "Allow" or "Deny" separately just like Windows permissions. This will allow more flexibility. Restricted file types can be set as "Allow" or "Deny". It's now possible to hide specific subfolders by denying all permissions. By default subfolders will inherit from parent but it's possible to stop inheritance at any level by adding an explicit access control.

  • Added: Completely redesigned the upload methods. New upload methods are Html5, Silverlight, Flash, Html4 in priority order. All methods provide accurate progress information.

    • Html5: This is the best one as it supports unlimited file size (via chunking), multiple selection at once and drag & drop. This method is available on IE 10 and all other recent browsers. You can also drag and drop files from local folders to the upload window with this method.

    • Silverlight: This is the second best one as it's similar to Html5 except it does not support drag & drop currently. Silverlight method can be a good alternative when users can not upgrade to browsers that support Html5. This method is also good for large files like Html5.

    • Flash: This supports multiple selection at once but it does not work well with large files due to problems in Adobe plugin. If you are uploading files larger than few hundred MBs of files, it will probably fail before even starting the upload. Flash plugin loads the whole file into memory which is inefficient and which causes a delay before starting the upload. However this method is different than the Flash method in previous versions as it will now retain cookies and authentication headers. This method should be only used when uploading small files and multiple selection at once is required.

    • Html4: This method works on all browsers. Browser and Ajax methods in previous versions is merged into this method. This method always provides progress information even if the application is hosted on a shared host (medium-trust) unlike previous Ajax method which required full-trust. This is the only method that chunking the file is not possible so there is a maximum limit of 2GB per file imposed by IIS and ASP.NET.

     

  • Added: When uploading a file that already exists, "Upload Conflict" dialog will be displayed. The user can either, upload and replace the file, skip the file or upload and keep both files by using an alternative name (eg. file(2).jpg). It's also possible to "do same for all conflicts" when there are multiple conflicts in the queue.

  • Added: Permission checks will be done before actually uploading the files and rejected files will be displayed beforehand. User can see the rejection reason by clicking on "Rejected" link in the status column.

  • Added: When uploading multiple files, the uploader will continue the other files even if a file fails. User can see the error details by clicking on "Failed" link in the status column.

  • Improved: During uploading, if user tries to navigate away from the page (eg. goes to new url or drops a file into the browser), interrupting will be prevented with a dialog window asking to leave or stay on the page.

  • Improved: Upload dialog will hide automatically on completion if there is no error and all the uploaded files will be automatically selected in the file listing for easily locating them.

  • Improved: Uploading and Uploaded events will be raised per group rather than per individual files. However both events provide properties for iterating all files and details in a group. It's possible to reject individual files with a reason in an Uploading event. More detailed upload information will be available in the Uploaded event. Status for each file such as Rejected, Skipped, Canceled, Failed, Completed and status reasons will be available. Also the total uploaded size, elapsed time and transfer rate will be available. Note that Failed event will not be raised when a file in a group fails from now on as the uploader will continue the other files even if a file fails. Instead, all errors will be saved and will be available when Uploaded event is raised at the end of a group.

  • Added: File/Folder chooser mode to FileManager control so that you can use the control as a Open/Pick or Save dialog in your web application. In chooser mode, "Choose" and "Cancel" buttons will be displayed at the bottom of the control and double-clicking on a item of allowed type will choose that item instead of doing the default action (download/explore). After user chooses items or cancels, the control hides and raises a client-side chosen event with event arguments.

  • Improved: Compatibility with IE 10.

  • Improved: Resources like js and css files will be always gzipped independent of IIS settings for extra performance. The pages hosting the FileManager control will load faster.

  • Improved: Prevented some unnecessary Failed events raised such as "Only http method POST is accepted" or "The remote host closed the connection". First error was caused by Firefox's built-in image viewer sending a second request for the same image or users/search bots trying to open temporary download URL manually. Second error was sometimes caused when users canceled an ongoing download.

  • Improved: Many minor issues are fixed and improvements are made.

Version 3.2.1 - December 4, 2012

  • Fixed: A vulnerability regarding paths.

  • Improved: The fix regarding "large file downloads and memory pressure" first applied in v3.1.1 is now undone as it had a side effect of limiting download speed to 800 kb/s. Now the download speed will be restored to the maximum. The actual source of the problem seems to be vanished and this may be related to an IIS hotfix.

Version 3.2 - May 29, 2012

  • Added: Touch support (especially for iOS devices iPad and iPhone) Context menus will now work by touching and holding on an item. Multiple items will be selected one by one or by touching and dragging over the items. Rendering is optimized, all UI elements (including pane separator) will work correctly, best possible font will be used. Downloads will work for supported files like image and text files. Unfortunately due to restrictions of Safari Mobile Browser on iOS, uploading files will not be possible.

  • Improved: Precision of context menus. Right-clicking on empty areas will be detected more correctly so the main context menu can be accessed more easily.

Version 3.1.1 - April 19, 2012

  • Fixed: Large file downloads (usually files bigger than 1GB) were sometimes interrupted to a memory pressure issue. This was experienced usually when the download speed was falling behind the streaming speed which caused internal buffer of IIS to expand constantly. With this fix, minimum (none or only few MBs) memory increase should be observed on the server during downloading large files.

Version 3.1 - February 17, 2012

  • Fixed: The JavaScript error below which occured only on IE 8 (it didn't occur in IE 8 compatibility mode of IE 9):
    "HTML Parsing Error: Unable to modify the parent container element before the child element is closed (KB927917)" Suggested workaround (adding a div element before the control) will not be necessary after this fix so it should be removed.

  • Fixed: When ID property of <GleamTech:FileManager> tag was missing, the control was not loaded/displayed. After this fix, even the ID property is missing, an ID will be auto-generated like "fileManager", "fileManager2", "fileManager3" etc depending on the number of FileManager controls on the host page.

  • Fixed: Incomplete/corrupted downloads problem in zip streaming feature (first introduced in v3.0.0) which occured when downloading large files due to a timeout issue. The problem did not occur with single file downloads. Note that zip streaming is active only when multiple items are downloaded or "Download As Zip" action is used explicitly. Previously suggested web.config workaround (executionTimeout setting) will not be necessary after this fix so it should be removed.

  • Fixed: Streamed zips (even small ones) could not be opened/unzipped with Archive Utility on Mac, the zip file structure is fixed to be compatible with this utility. Note that when the size is larger than 4GB, zip file must be generated in zip64 format instead of the regular format. Some older unzippers like Windows XP Explorer and Mac Archive Utility (maybe not newer versions) do not support zip64 format so you may need to use a more recent unzipper (Mac Unarchiver, Winzip, Winrar etc.) for files larger than 4GB on these systems.

  • Improved: Zip files will be generated with no compression (files are stored) during zip streaming so that CPU usage is minimized. There are two additional advantages due to this improvement other than server performance. First advantage is, we can simulate the zip generation and determine the zip file size exactly (and fast) before streaming. This was not possible previously so the browser showed indeterminate progress information (chunked transfer encoding) during download due to lack of knowing the final file size. So now the browser will show the exact zip file size on its "Open/Save As" dialog immediately after user clicks "Download As Zip" and it will show a determinate progress information on "Downloading" dialog. In short, zip streaming will behave exactly like single file downloads. Second advantage is, the users will be able to extract the received zip file very fast as there is no compression. This would be helpful when downloading large files and folders. Users who want to actually compress files should use "Add To Zip" action instead of "Download As Zip" and then download the generated zip file.

  • Fixed: Some unnecessary Failed events were being raised when the download was interrupted mostly due to user cancelling the download.

  • Improved: On Upload dialog, Ajax and Flash menu items will be disabled on the main context menu's submenu "Upload Method" when these methods are not available to prevent confusion for the user. Flash menu item will be disabled when Adobe Flash Player is not found or enabled in the browser. Also "Add" button will be enabled only when Flash object is loaded completely to prevent user clicking the button too early. Ajax menu item will be disabled when the application is running on ASP.NET medium trust which does not allow Ajax upload method. Note that these upload methods were already disabled and degraded to the next best method when not available. This improvement is only for UI to report the available upload methods to the user correctly.

  • Improved: Moved and organized all FileUltimate related Web.config settings to a separate file "FileUltimate/Web.config" for easier deployment and more security. Only exception is the upload module setting which has to still exist in the application's root Web.config file due to ASP.NET's handling of http modules. FileUltimate settings like handler urls and max upload size will be determined dynamically via parsing "FileUltimate/Web.config" file. For security reasons, maxAllowedContentLength and maxRequestLength settings will be increased to 2GB only for the upload handler. The default IIS and ASP.NET limits is sufficient for other handlers so keeping them at default values will protect against DoS attacks.

  • Changed: Renamed resource folder under App_GlobalResources from FileUltimate to FileUltimateResourceStore.

  • Fixed: The below error that may occur when trying to download a file which was opened in some rare applications which locks the file in write-only mode:
    "The process cannot access the file ‘file name’ because it is being used by another process"

  • Fixed: All CSS files are minified like JavaScript files now.

Version 3.0.8 - January 12, 2012

  • Improved: Browsing huge folders is vastly improved (thousands of items will be displayed very quickly) with Browser rendering optimizations.

  • Added: IsRefresh property to FileManagerTraversingEventArgs, FileManagerTraversedEventArgs, FileManagerListingEventArgs and FileManagerListedEventArgs to be able to distinguish between a refresh and a new action.

  • Added: New better icon (blue version of subfolder icon) for root folder.

  • Improved: The look of grid columns so that they look more similar to the columns in Windows Explorer.

  • Improved: Rendering icons in TreeView and GridView so that they are aligned more precisely respective to text.

  • Improved: Used HTML5 markup for some auto-generated responses (error and expired page).

Version 3.0.2 - October 20, 2011

  • Added: UploadQueue property is now available in Uploaded event for accessing all the previously completed uploads in a queue. Starting with v3.0, Uploaded event is raised per file as files are processed one by one by the upload dialog for better performance and statistics. One other advantage is 2GB upload limit will effect files individually so there will be no limit for the total size of the files added in the upload dialog. However the disadvantage was you had to do an action for every single file (eg. send multiple emails) as Uploaded event was raised for each file. For solving this problem, this new property UploadQueue is added. "UploadQueue.IsCompleted" will allow you to do an action (eg. send an email) only when the last item in the queue is processed, ie. when the queue ends. "UploadQueue.UploadInfos" will allow you to loop through all completed UploadInfo objects for collecting information about previous uploads in the queue.

  • Improved: Used gradients (instead of single color) for selections in file listing, folder tree and context menus for an improved Windows 7 look.

Version 3.0 - August 10, 2011

  • Almost rewritten both client-side and serder-side code for maximum performance, stability and flexibility. Client-side code is now organized with namespaces like GleamTech.JavaScript.UI and classes. This organized structure will provide a proper client API and allow new features to be added more easily. Changed server-side namespace to GleamTech.Web.UI.

  • FileUltimate is now the general product name of the "ASP.NET File Handling Controls" library. The main control is renamed from FileUltimateControl to FileManager. Other standalone controls (eg. FileUploader) may be added to FileUltimate in future versions.

  • Completely new UI with Windows 7 look and feel. All UI images are updated. All file type icons are updated and lots of new ones are added.

  • Almost rewritten and modularized upload feature. UI of upload dialog is vastly improved. Even with browser upload method, detailed progress information will be shown. It’s possible to change upload method via context menu.

  • Improved: Dropped support for IE 6. Minimum required version for Internet Explorer is now 7. Optimized for new generation of browsers like IE 9, Firefox 5, Chrome 12 and Safari 5.

  • Improved: "Download As Zip" action now directly streams the zip file that is being generated to the client. So the user will not have to wait for the whole compressing to complete before downloading. The user will see browser's "Open / Save As" dialog immediately and receive the file on the fly as it is being generated.

  • Added: Multiple instances of the control on the same page is now possible.

  • Added: ShowOnLoad property to control visibility of the control on load.

  • Added: ModalDialog and ModalDialogTitle properties for displaying the control within a modal dialog.

  • Added: ClientLoaded property to specify the client-side event which is raised on load.

  • Added: SortRootFolders property to control sorting order of root folders.

  • Changed: Dropped Style property and added Width and Height properties to specify the dimensions of the control.

  • Changed: Dropped FullScreen and added FullViewport property for fitting the browser's viewport.

Version 2.1 - September 3, 2010

  • Product name is changed from FileVistaControl to FileUltimate so that the control product is not confused with the end-user product (FileVista).

  • Single DLL deployment. FileUltimate is from now on, a WebControl and not a UserControl (ascx control). All resources and code are embedded into the single file GleamTech.FileUltimate.dll for easy and robust deployment.

  • FileUltimate now targets .Net framework 4.0. This means your host project should run under ASP.NET 4.0. We will not support older framework versions from this version on.

  • Developed a custom embedded resource manager which can combine resources like scripts.

  • Vastly optimized loading speed of the control by making use of combined scripts and reducing the number of requests.

  • Optimized zip features.

  • Changed some namespaces and type names.

  • Optimized download feature.

  • Added: ShowFoldersPane property to control visibility of the Folders pane.

  • Added: Embedded languages files and the css file can be overridden with custom files, see readme file for more information.

  • Fixed: When a subfolder is copied or moved to a root folder, every folder was displayed twice in the Folders pane incorrectly due to a refresh problem.

  • Fixed: "The destination folder is a subfolder of the source folder" was being raised incorectly when copying/moving a folder eg. named "Test" into a folder named eg. "Test Folder".

  • Improved: Reorganized event arguments for Uploading and Uploaded events and restructured UploadedFile class. UploadedFile.FileHash property will provide the calculated hash code of the uploaded file in all three upload modes (Flash, Ajax and Browser) correctly .

Version 2.0 - June 15, 2010

  • Added: FileVistaControl will be able to run under ASP.NET "Medium" trust level from now on. Many shared-hosting companies (eg. GoDaddy) force Medium trust level on their servers for security reasons and FileVistaControl will be compatible with them now.

  • Added: A third upload method and optimized existing upload methods. Renamed the old upload method "Browser" to "Ajax" and the new upload method to "Browser". New "Browser" method will allow uploading even in medium-trust level by sacrificing the realtime progress information. "Ajax" method (formerly "Browser") still needs higher permissions due to displaying the realtime progress information so it will not be available in medium-trust level. Note that the best possible upload method "Flash" will now work in medium-trust level.

  • Added: New property "ShowSystemTypeDescriptions" for forcing to show file and folder type descriptions from the system's registry. If not enabled (default behaviour), then simple (but current language dependant) type descriptions (eg. EXE File) will be shown. Under Medium-Trust, registry access will not be possible so even if this property is enabled, simple type descriptions will be shown.

  • Fixed: Modal dialog background rendering error occured for certain layouts in IE7 only (like in Example 3)

  • Fixed: Refresh problem which occured only when you paste after entering into the subfolder.

  • Fixed: Allowed file types checking was failing due to checking the full path instead of the file name.

  • Fixed: Firefox 3.6 context menu event handling problem.

  • Improved: Control and context menus rendering, calculating dimensions, automatic resizing with percentage values.

  • Changed: Added and changed some language strings in the language files with key numbers 315 till 317.

Version 1.9 - March 22, 2010

  • Added: Spanish, Catalan, Danish and Portuguese language files.

  • Added: Support for cookieless session state.

  • Added: Downloading files larger than 2 GB is now possible.

  • Added: New property "MaxZipFileSize" for limiting the size of the generated zip files on "Add to Zip" and "Download as Zip" actions. If this property is not set, then there will be no size limit for the zip files just like the previous behaviour.

  • Added: Detailed information (action size, remaining size and total quota) will be displayed when an action (Upload, Add to Zip, Extract and Paste) exceeds the quota limit of the folder.

  • Added: New property "ShowHiddenFilesAndFolders" for forcing to show hidden files and folders.

  • Added: New property "ShowSystemFilesAndFolders" for forcing to show system files and folders.

  • Added: New property "ShowFileExtensions" for forcing to show the extension part of the file names. When this property is enabled, the extensions will be shown and editable in the prompt dialog boxes too. For instance, on "Rename" and "Add to Zip" actions, changing the extension part is possible. The actions will fail if the new extension does not match the allowed types of the folder.

  • Added: Detailed information (file name, allowed file types) will be displayed when the result of an action (Rename, Add to Zip, Upload) does not match the allowed file types of the folder.

  • Added: The control will now also raise before events: Browsing, Creating, Deleting, Renaming, Copying, Moving, Compressing, Extracting, Uploading and Downloading. A before event can be canceled with displaying a message to the user. If a before event is canceled, the corresponding action will be canceled and the after event will not be fired.

  • Added: New property "FileListColumns" for accessing the columns of the file list. Currently only the size (number of characters) of the columns can be overridden.

  • Added: Context menus for the folder tree. It is now possible to do all actions by right clicking a folder in the tree.

  • Improved: Context menu for container folder will be opened when right-clicked on an empty area in the file listing. When right-clicked on the text (name or other properties) of an item row in the file listing, the item will be selected and context menu for the item will be opened. Removed "Tasks" link above the file listing as it's replaced with the context menu.

  • Improved: Mouse cursor will be shown as the pointer (hand) only when on a folder in the folder tree and not on the file listing or the toolbar buttons for a more standard UI.

  • Improved: Selected item name will be used as the zip file name instead of the generated names like "download-XXXX.zip" when downloading as zip.

  • Fixed: Download corruption with some files types like PDF when IIS dynamic compression is enabled.

  • Fixed: A confirm dialog box will be displayed when downloading as zip. This will prevent IE from showing the information bar and blocking the download.

  • Fixed: Adding files with the same names will not be allowed in the upload dialog.

  • Fixed: Add to Zip, Download, Cut and Copy actions will now also depend on Traverse and List permissions of the subfolders. These actions may access the contents of a subfolder so they should be checked against Traverse and List permissions.

  • Fixed: Quota limit will be checked before starting the actions (Add to Zip, Extract and Paste). If the total size of the action exceeds the quota limit, the action will be canceled. This will prevent the action from being completed partially. In previous versions, the action was being processed until a file's size exceeded the quota limit. This was causing partially extracted/pasted files.

  • Fixed: Quota limit will not be checked when moving items from a subfolder to a parent folder and vice versa unless the subfolder has an overridden quota setting. A parent folder's total size already includes the size of the subfolders so moving items within the parent folder can not effect the remaining quota size.

  • Fixed: An extension in allowed file types such as "*.jpg", was matching all extensions starting with "jpg" ("*.jpg1", "*.jpga" etc.) where it should match only "*.jpg"

  • Fixed: The control will now render properly when placed within an invisible container (eg. tab panels).

  • Fixed: Right-clicking (or CTRL + click) now opens the context menu in Firefox Mac. On Mac, Command + click will now allow multiple selection instead of CTRL + click as on Windows.

  • Changed: Added and changed some language strings with key numbers 304 till 316.

Version 1.7 - June 5, 2009

  • Fixed: Optimized the clickable area of the Add button in browser mode for cross-browser compability.

  • Fixed: Marked the new class FileVistaFolder as Serializable for the out of process session state.

  • Fixed: Upload dialog missing progress indication in Firefox 2.

  • Added: Hidden and system files/folders are filtered by default.

  • Added: 5 new upload related strings to the language files.

  • Added: French and Arabic language files.

  • Improved: Speed of file listing in the folder view and subfolder populating in the folder tree.

  • Added: New property "DisableFolderExpandableCheck" which can be set to true if you are experiencing slow load times with huge folders. When building the folder tree, the control calculates if a folder is expandable or not (ie. if it should have a plus sign or not). By setting this property to true, you can disable this calculation and improve loading speed of huge folders.

  • Fixed: If a root folder is inaccessible due to insufficient permissions or other problems, it will still be displayed in the folder tree. This will allow to ignore the root folder with problems and continue loading other available root folders in the list.

  • Fixed: Copying or moving a folder into its subfolder will not be allowed.

  • Added: Extensions of file names are hidden in the file listing.

  • Fixed: The default value of a root folder's AllowedFileTypes property is now "*" instead of "*.*". This will allow files without extensions by default when the property is not set to a specific value.

  • Added: When List permission is denied on a folder, an empty folder will be displayed instead of an error message so that other permitted actions can be still done in the folder. This way "blind uploads" and "traversing subfolders without showing files" will be possible.

  • Added: A root folder's AllowedFileTypes property will now restrict all file actions (List, Delete, Rename, Copy, Move, Extract, Compress and Download) and not only Upload action. This means only allowed file types will be visible and manageable in the file listing.

  • Added: Edit permission now controls overwriting of existing files during Extract action and editing of an existing zip file during Add to Zip action.

  • Fixed: Folder tree will be refreshed properly on Cut and Paste of folders.

Version 1.6 - October 31, 2008

  • Added: Advanced security system which allows assigning access control (permissions, quota and allowed file types) for each subfolder of a root folder separately.

  • Added: New property "TemporaryFolder which will control the location of the temporary files that are created during actions like "Download As Zip". If omitted, temporary files will be created in the same folder where the action occurs.

  • Improved: Flash upload compatibility with Adobe's latest flash player version 10.0.12.36.

  • Fixed: Text could not be selected in the prompt dialog on IE.

  • Improved: Enter and Esc keys now work same as the OK and Cancel buttons in the prompt dialog.

  • Fixed: A warning message will be displayed on Paste, Compress, Extract All actions when the folder reachs its quota limit.

Version 1.5.9 - July 18, 2008

  • Fixed: Timeout problems occured with long lasting uploads in Flash upload mode.

  • Improved: Detailed errors instead of generic errors will be displayed and upload event will be logged more accurately in Flash upload mode.

Version 1.5.8 - July 4, 2008

  • Fixed: Upload problem which occured in Flash upload mode when uploading more than one file at once. The error was occuring when one of the files took long time to finish, causing a timeout and stopping the overall upload with an error message.

Version 1.5.7 - June 19, 2008

  • Fixed: "Download" and "Open with Web Browser" actions will also refresh the host page when when session expires.

  • Fixed: Files and folders with the "Read-only" attribute can now be deleted.

  • Fixed: Event was not raised when single file was uploaded in flash upload mode.

  • Changed: Removed the 2GB maximum limit of maxUploadSize property of FileTransfer section in web.config to allow overriding the value.
