ExcludedExtensionsForPreview does not exclude file extensions from preview

Problem reported by Lara Newsom - 1/26/2018 at 9:34 AM

Not A Problem

Any idea why ExcludedExtensionsForPreview is not working? I've also tried it with "*" and ".*" which also does not work. We want to disable all previewing since we are not able to pre-cache the files and some of our documents are taking over a minute to load in preview.

We are currently using FileUltimate version 5.16.0 and GleamTech.Core version 2.0.1

            FileManager fileManager = new FileManager()
            {
                Width = Unit.Percentage(80),
                Height = 500,
                Resizable = true,
                DownloadOnDoubleClick = false,
                ViewLayout = ViewLayout.MediumIcons,
                ExcludedExtensionsForPreview = ".pdf, .xls, .doc, .docx"
            };

Hi,

Firstly you should not include dots before extensions in the property:

ExcludedExtensionsForPreview = "pdf, xls, doc, docx"

This way the property would work as expected but you would still need to list all extensions (no match-all setting here).

For disabling all previewing, instead you should deny Preview permission for your root folder:

var rootFolder = new FileManagerRootFolder
{
    Name = "My root folder",
    Location = "c:\root\folder"
};

rootFolder.AccessControls.Add(new FileManagerAccessControl
{
    Path = @"\",
    AllowedPermissions = FileManagerPermissions.Full,
    DeniedPermissions = FileManagerPermissions.Preview
});      

fileManager.RootFolders.Add(rootFolder);
