    Hi,

    I have aproblem in uploading *.mht files using the Document Manager of the RadEditor control. By selecting the required *.mht file and click Upload I get the "Internet Explorer cannot display the webpage" error.

    Here is my Code:
    string searchPatterns = "*.doc,*.txt,*.docx,*.xls,*.xlsx,*.pdf,*.xml,*.zip,*.rar,*.mht";
    CntntRadEditor.DocumentManager.SearchPatterns = searchPatterns.Split(',');

    By the way, I can upload all file types except to *.mht files, and there is no maximum upload size problem (File size is 4.5 MB and the MaxUploadFileSize is 30 MB).

    Can you please explain to me how can I upload such files using the Document Manager.

    Regards,
    Bader

    Bader:

    I cannot reproduce your failure. I am able to upload an .mht file using the following code. See the attached image ("radeditor_documentmanager_upload.png") for the results.  I used your server-side code to set the search pattern.

    Default.aspx:

    <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="Default" %>
    <%@ Register TagPrefix="telerik" Namespace="Telerik.Web.UI" Assembly="Telerik.Web.UI" %>
     
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
     
    <head runat="server">
        <title></title>
        <telerik:RadStyleSheetManager id="RadStyleSheetManager1" runat="server" />
    </head>
    <body>
        <form id="form1" runat="server">
        <telerik:RadScriptManager ID="RadScriptManager1" runat="server">
            <Scripts>
                <%--Needed for JavaScript IntelliSense in VS2010--%>
                <%--For VS2008 replace RadScriptManager with ScriptManager--%>
                <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.Core.js" />
                <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQuery.js" />
                <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQueryInclude.js" />
            </Scripts>
        </telerik:RadScriptManager>
        <script type="text/javascript">
            //Put your JavaScript code here.
        </script>
        <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
        </telerik:RadAjaxManager>
        <div>
        <telerik:RadEditor DocumentManager-ViewPaths="~/Uploads" DocumentManager-UploadPaths="~/Uploads" ID="RadEditor1" runat="server" DocumentManager-MaxUploadFileSize="2048000"></telerik:RadEditor>
        </div>
        </form>
    </body>
    </html>

    Default.aspx.cs:

    using System;
    using Telerik.Web.UI;
     
    public partial class Default : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            string searchPatterns = "*.doc,*.txt,*.docx,*.xls,*.xlsx,*.pdf,*.xml,*.zip,*.rar,*.mht";
     
            RadEditor1.DocumentManager.SearchPatterns = searchPatterns.Split(',');
        }
    }

    The selected upload is "Toolbars.mht" and it is 1.27 mb.

    Have you tried uploading smaller .mht files to see if this relates to an upload timeout issue? Are you able to successfully upload other file types such as .zip or .rar files that are 4.5mb in size?

    Cheers!

    Hi guys,

    If the uploaded file size exceeds the default ASP.NET limit of 4 MB then the framework will throw error and you will experience the reported problem. The solution is provided in the following help article: Uploading Large Files Using Editor (maxRequestLength).
