    Q2 2011 Service Pack 1 (Version 2011.2.915)

    Breaking change:      Now all HTML 5 compliant browsers, which support the File API interface (FireFox 4.0+, Chrome latest, Safari 5.0+), use the File API module.

    Reason:     Numerous of problems with the Silverlight/Flash plugins in browsers different than IE. The FileAPI module provides the same features as Flash/Silverlight with one exception. It is not yet possible to display extensions filter within the select file dialog. However, this functionality is part of the input[type='file'] specification and it is about time that the browsers implement it.

    Problem:     Using the Flash module in IE6/7/8 debug information is displayed into the Developers Bar JavaScript console.

    Reason:      Non commented console.log invocation within the ActionScript code.

    Solution:     The problem will be resolved in the upcoming Latest internal build.

    Q2 2010 (Version 2011.2.713)

    Problem    : RadAsyncUpload sometimes fail to upload the files to the target folder.

    Reason: The temporary files, which RadAsyncUpload uses internally to save the uploaded files to the target folder, are being deleted too early, hence leaving the upload without files to save.

    Solution: We have fixed the problem for the latest internal build (version 2010.2.722+). More information on how to obtain the latest internal build can be found here.

    Alternatively, you can do the following:

    Step 1: Add an ashx handler to your app. Inside, use the following code:

    <%@ WebHandler Language="C#" Class="CustomHandler" %>
     
    using System;
    using System.Web;
    using Telerik.Web.UI;
     
    public class CustomHandler : AsyncUploadHandler {
     
        
        protected override IAsyncUploadResult Process(UploadedFile file, HttpContext context, IAsyncUploadConfiguration configuration, string tempFileName)
        {
            configuration.TimeToLive = TimeSpan.FromHours(4);
            return base.Process(file, context, configuration, tempFileName);
        }
     
    }

    Then, set the HttpHandlerUrl property of RadAsyncUpload to point to that handler. Like this:

    <telerik:RadAsyncUpload runat="server" ID="RadAsyncUpload1" HttpHandlerUrl="~/CustomHandler.ashx" TargetFolder="~/Documents">
            </telerik:RadAsyncUpload>
