    I have a question about functionality of this control.

    Here is my scenario: I have an ASPX page with a RadWindow that has a ContentTemplate that appears from clicking a button. Nothing complicated, the button just does this

    OnClientClick="openUploadWindow1(); return false;

    Inside of the RadWindow that opens I have (among other controls) a RadAsyncUpload control that automatically uploads a file to the default temporary directoy and a DIV that contains the image of a file that is saved to a database. What I'm trying to do is the following:

    Someone uploads a TIFF image through the RadAsyncUpload tool. I would like to display this image in the aforementioned DIV as soon as the image is finished uploading to the temporary directory. However, TIFFs can't be viewed normally in a browser, so I would need to post-back to the server to convert it to a JPG, PNG, or BMP and then display that image. However, I don't see a method that handles this scenario.

    In brief I want to:
    • Open a RadWindow
    • Select a file that is immediately uploaded via RadAsyncUpload in that RadWindow
    • As soon as it's finished, call some server-side function or at least post-back to the server
    • Convert the image to a JPG
    • Re-open the dialog box with the controls on my RadWindow with the same information

    This since it's posting back it sounds like more a job for RadUpload, but there's most likely functionality in RadAsyncUpload that I don't know about.

    Thank you for your time.

    Actually, what I ended up doing was the following:


    to the RadAsyncUpload control in the ASPX file.

    Added this in my Javascript:

    function uploadPostBack1() {
        "use strict";
        var uploadName = document.getElementById('<%=DialogTextBox1.ClientID%>').value;
        __doPostBack("Upload1", uploadName);

    From here I could just call 

    UploadWindow1.VisibleOnPageLoad = true;

    from the Page_Load event after I ran my own code to get the image. If you happen to run this in the Page_Load however, take note that any postback could cause the  window to keep re-appearing so set the above to false first, run your desired code, and if you need the window then do the VisibleOnPageLoad = true again.

    Hopefully this helps someone out. I'll be watching the thread just in case someone wants to do something similar.

    Well, turns out it's still not quite working how I would like...

    Here is my updated situation. I have a RadWindow with a RadAsyncUpload control inside of it. The RadWindow is using an actual ASPX page, not a template. When the user uploads a file, it is set to immediately reload the radWindow because the file the user uploads will be a TIF and I need to create a JPG copy of it server side and then display that image (but keep copies of them both to store in a database when I hit a save button)  but I can't access the files from the radasyncupload control in the code-behind after I reload the radwindow as the count of uploaded files is 0.

    I tried the PostBackTriggers, but that didn't seem to do anything for me.
    Any ideas? Thanks in advance.

    Code for reloading the RadWindow:
    <script type="text/javascript">
                /*global getRadWindow, uploadPostBack1 */
                function getRadWindow() {
                    var oWindow = null;
                    if (window.radWindow) oWindow = window.radWindow;
                    else if (window.frameElement.radWindow) oWindow = window.frameElement.radWindow;
                    return oWindow;
                function uploadPostBack1() {
                    var thisWindow = getRadWindow();

    Bah, I figured it out. I wish I could delete my thread.
