Trying to set document to be loaded from code behind

Not A Problem

HI,

I am currently evalutingDoucmentUltimate and trying to set the document to be loaded from the code behind in my webforms application.

            <GleamTech:DocumentViewerControl runat="server" 
                Width="800" 
                Height="600" 
                Document="~/Documents/test" />

Could someone please provide a simple example,

I tried the following:

 DocumentViewerControl.Document = "~/TestDocument.doc"

Error 25 'DocumentViewerControl' is not declared. It may be inaccessible due to its protection level. WordExcelTest.aspx.vb

Could someone please provide a simple example.

You need to access any ASP.NET WebForms control via it's ID in codebehind. When not specified the default ID for DocumentViewerControl is "documentViewer" so you can use this:

documentViewer.Document = "~/TestDocument.doc"

or you can specify a custom ID:

<GleamTech:DocumentViewerControl runat="server" 
        ID="documentViewer2"
        Width="800" 
        Height="600" 
        Document="~/Documents/test" />

Many thanks for replying.

When I add this:

<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="WordExcelTest.aspx.vb" Inherits="OandViewSample.WordExcelTest" %>

<%@ Register TagPrefix="GleamTech" Namespace="GleamTech.DocumentUltimate" Assembly="GleamTech.DocumentUltimate" %>
<%@ Register TagPrefix="GleamTech" Namespace="GleamTech.DocumentUltimate.AspNet.WebForms" Assembly="GleamTech.DocumentUltimate" %>

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">;
<head runat="server">
<title></title>
</head>
<body>
<form>

<GleamTech:DocumentViewerControl runat="server"
ID="documentViewer2"
Width="800"
Height="600"
Document="~/Documents/test" />
</form>
</body>
</html>

I receive an error:
Error 1 Type 'GleamTech.DocumentUltimate.AspNet.WebForms.DocumentViewerControl' is not defined. WordExcelTest.aspx.designer.vb 23 45

I also tried your other option:
<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="WordExcelTest.aspx.vb" Inherits="OandViewSample.WordExcelTest" %>

<%@ Register TagPrefix="GleamTech" Namespace="GleamTech.DocumentUltimate" Assembly="GleamTech.DocumentUltimate" %>
<%@ Register TagPrefix="GleamTech" Namespace="GleamTech.DocumentUltimate.AspNet.WebForms" Assembly="GleamTech.DocumentUltimate" %>

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">;
<head runat="server">
<title></title>
</head>
<body>
<form>
<GleamTech:DocumentViewerControl runat="server"
Width="100%"
Height="800"
Document="~/Documents/790-61010.dwg" />
</form>
</body>
</html>

CODE BEHIND:
Public Class WordExcelTest
Inherits System.Web.UI.Page

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

documentViewer.Document = "~/TestDocument.doc"

End Sub

End Class

I receive an error:
Error 3 'documentViewer' is not declared. It may be inaccessible due to its protection level. WordExcelTest.aspx.vb 7 9

Many thanks for any help

Well, did you add References to GleamTech DLLs in your project?
Please follow "Getting Started" guide here:
https://docs.gleamtech.com/documentultimate/html/adding-references-to-documentultimate-assemblies.htm
Also examine the example VB project included in the download from our site.
