  Here's the issue:
  
  When I have a RadUpload control on the page and then do any type of Ajax call before a submit, there is repeated calls to Raduploadprogresshandler.ashx until the browser is shut down. This issue was also documented here:
  
  http://www.telerik.com/community/forums/aspnet-ajax/upload/mulitple-requests-to-telerik-raduploadprogresshandler-ashx.aspx 
  
  but, I tried both of those fixes and neither worked completely. Adding:
  
  <add key="AllowCustomProgress" value="false"/> 
  
  to the web.config worked, but only if the RadUpload control did not have a file already selected.
  
  What is the correct way of avoiding this issue?
  
  Thanks!
  
  - Mike

  Hi Mike,
  
  The workaround suggested in the forum thread you have mentioned  is indeed valid only when there is no file selected in the RadUpload. Please try to add the following code , right after the declaration of your RadScriptManager or ScriptManager:
  

  <script type="text/javascript">

   

              Telerik.Web.UI.RadProgressManager.prototype._clientSubmitHandler = function (eventArgs) {

                   

                  var cancelArgs = new Sys.CancelEventArgs();

   

                  this.raiseEvent('submitting', cancelArgs);

                  if (cancelArgs.get_cancel()) {

                      return $telerik.cancelRawEvent(eventArgs);

                  }

   

                  if (!this._allowCustomProgress) {

                      var hasFiles = false;

   

                      var inputs = $telerik.$("input[type='file']");

                      $telerik.$.each(inputs, function () {

                          if (this.value != "" && !Sys.WebForms.PageRequestManager.getInstance().get_isInAsyncPostBack()) {

                              hasFiles = true;

                              //exit the loop

                              return;

                          }

                      });

   

                      if (!hasFiles)

                          return;

                  }

              }

          </script>

  Hi,
  
  I code snippet above does the trick, thanks! Is this workaround going to be fixed anytime soon? That is - should I remove this fix after the next release?
  
  Thanks,

  Hi Mike,
  
  I'm glad that the overwrite provided is working for you. As for your question, yes this will be fixed in some of the upcoming internal builds, so my suggestion is to keep track of the release notes. This way when the issue is fixed you could remove the unnecessary code.
