    I just noticed something strange while I was testing for an unrelated issue.

    I have a RadTreeView that loads content into a RadTabStrip/Mulitpage. In one of the tabs I have a RadUpload control. The tree and the tabstrip are Ajaxified.

    When I click on a node in the TreeView it loads the relevant content in the tabs. However, I have just noticed while monitoring my application with Fiddler that after the inital load I get multiple (infinite?) calls to: http://servername:8070/Telerik.RadUploadProgressHandler.ashx?RadUrid=784e5751-9181-4e49-bb82-44cd26a3f791&RadUploadTimeStamp=1281621267773&

    These keep on going until I kill the browser. At the point in which this is happening no file has been selected for upload. The upload tab isn't even visible at this point.

    Have I set my RadUpload up incorrectly? Why is this happening?

    Thanks,
    Scott.

    Hi Scott Marsh,

    This is a known issue with RadProgressManager. There are multiple ways to fix it, but the easiest is to navigate to the web config, find the appSettings section and add the following setting there:

    <appSettings>
      <add key="AllowCustomProgress" value="false"/>
    </appSettings>

    Hi Jon Vickers,

    Other workaround is to put the following code right after the ScriptManager declaration:

    <script type="text/javascript">
            var prm = Sys.WebForms.PageRequestManager.getInstance();
            var originalClientSubmit;
       
            if (!originalClientSubmit) {
                originalClientSubmit =
    Telerik.Web.UI.RadProgressManager.prototype._clientSubmitHandler;
            }
      
            Telerik.Web.UI.RadProgressManager.prototype._clientSubmitHandler = function(e) {
                if(!prm._postBackSettings.async) {
                    originalClientSubmit.apply(this, [e]);
                }
            }
        </script>

    Do these fixes apply when I want to use the CustomProgress features of RadUpload? I've tried the second fix and now my custom progress tracker doesn't show up at all. Am I able to prevent the repeated calls to the handler while using the CustomProgress

    Thanks

    Hi Scott,

    No, the current implementation only covers the cases where upload monitoring is in progress. Please note that in custom progress scenarios you can simply call the cancel method of RadProgressArea as soon as the job being monitored is done. If you have any troubles following the suggested workaround please open a support ticket and provide there more details regarding your scenario.

    I lost 3 hours over this error today. You know for this error since 2010 and you haven't fixed it in this time. Why?! I'm using DNN.

    Hi Log,

    We have discontinued our partnership with DNN and we do not provide support for it. If you manage to isolate this in a runnable project please open new support ticket and attach this project. We will do our best to give you reasonable solution.

    Thanks.
