    Hi,

    I have a situation where I need to move a RadAsyncUpload control in the DOM.  After I move it the AllowedFileExtensions seems to be reset to allow all extensions.  I have not been able to work out how to set the AllowedFileExtensions via javascript.

    Here is the problem isolated in a simple example.  Initially only jpg and wmv files can be selected.  But once I click the bt_MoveDiv button and move the control in the DOM, all file types can be selected.

    <body>
        <form id="form1" runat="server">
         
        <script language="javascript" type="text/javascript">
         
            function buttonClick() {
                var container = document.getElementById('container');
                var ph = document.getElementById('holder');
     
                ph.appendChild(container);
            }
         
        </script>
         
        <div>
            <telerik:RadScriptManager ID="RadScriptManager1" runat="server">
            </telerik:RadScriptManager>
         
            <div id="container">
                <telerik:RadAsyncUpload ID="RadAsyncUpload1" runat="server" AllowedFileExtensions="jpg,wmv">
                </telerik:RadAsyncUpload>
                <telerik:RadProgressArea ID="RadProgressArea1" runat="server">
                </telerik:RadProgressArea>
                <asp:Button ID="bt_Submit" runat="server" Text="Submit" onclick="bt_Submit_Click" />
            </div>
             
            <div id="holder">
            </div>
             
            <asp:Button ID="bt_MoveDiv" runat="server" Text="Move div" OnClientClick="buttonClick();return false;" />
             
        </div>
        </form>
    </body>

    I had similar problems some time ago with RadEditor being moved in the DOM.  This problem was fixed with the onParentNodeChanged() function.  Is there something similar I can do for RadAsyncUpload?

    Thanks
    Andrew

    Hi Andrew Dixon,

    A possible solution is to use the Flash module to upload files. You need to disable your Silverlight module. Please add the following code to your page:
    <script language="javascript" type="text/javascript">
                 Telerik.Web.UI.RadAsyncUpload.Modules.Silverlight.isAvailable = function () { return false; };
    </script>

    Another solution is to check the allowed file extensions client-side with the method get_allowedFileExtensions(). For more details refer to the help article.

    Hi Peter,

    Adding that line to my javascript seems to have fixed the problem.

    Thanks
