    Hi - 

    We're using the 2010.3.1317 version of RadAsyncUpload control. We've had to turn off the silverlight and flash modules because they cause problems for our MAC clients. After turning these off though the control no longer works in IE8 ( running IE8 document mode and browser mode). The issue is that when you click the select button of the control the upload dialog does not appear. 

    Any ideas?

    Could you please open a support ticket and send us a sample which demonstrates the issue to examine it locally?
    Otherwise do you experience the same issue at our online examples when silverlight and flash are disabled?

    Kind regards,

    When i upload file from IE8 , my file is correctly uploaded but , the file name and extension is not correct in the temp folder.

    Source  : sample.txt
    TempFolder : jsu3cxhz.5gu 

    If i change the extension of my target file i can open it normaly. 

    <telerik:RadAsyncUpload MultipleFileSelection="Disabled" MaxFileInputsCount="2" runat="server" ID="AsyncUpload1" ManualUpload="false"  TemporaryFolder="~/File/UploadedFilesTemp" EnableFileInputSkinning="true" DisablePlugins="true" Skin="Metro" TargetFolder="~/File/UploadedFiles" />

    I tried to disable flash or Silverlight but i have always this bug.

    Telerik.Web.UI.RadAsyncUpload.Modules.Flash.isAvailable = function () {
                return false;
            Telerik.Web.UI.RadAsyncUpload.Modules.Silverlight.isAvailable = function () {
                return false;

    Why my file is not uploaded correctly when i'm on IE8... ? 

    Could you help me please

    Hi Spdev,

    The TemporaryFolder of RadAsyncUpload will save files temporarily until a postback occurs.The file name in temporary folder will be some fake name that is the default behavior of RadAsyncUpload. The TargetFolder will give the correct file name  of the uploaded file. Please have a look into the following  code that I tried to access the file name from temporary folder after postback occurs.

    protected void RadAsyncUpload1_FileUploaded(object sender, Telerik.Web.UI.FileUploadedEventArgs e)
        string targetFolder=RadAsyncUpload1.TemporaryFolder;
        Response.Write(Server.MapPath(targetFolder + "/" + e.File.FileName));

    Hi Shenu

    Thanks a lot for your answer,I tried your proposition, you're right after a postback file is rename with the good name and extension.

    But in my case,i cannot do a postback.  The radasyncupload is in radwindow , and that is in UpdatePanel.
    How can i have directly in the temp folder the good file name when i use IE8 (Silverligth) ?

    Hi Alexandre,

    Please try the following code snippet that I tried to access the Uploaded FileName in Client side.

    <telerik:RadAsyncUpload ID="RadAsyncUpload1" runat="server" TargetFolder="Uploads"

    <script type="text/javascript">
        function OnClientFileUploaded1(sender, args) {
