  Requirements
  RadControls version	Telerik.Web.UI 2007.3.12.18+ or RadUpload v.2.3.0+
  .NET version	NET 2.x/3.x
  Visual Studio version	2005/2008
  programming language	JavaScript, C#
  browser support	all browsers supported by RadControls

  
  
  PROJECT DESCRIPTION
  The project demonstrates how to monitor custom progress without making a postback but using RadAjaxManager instead.

  SOLUTION
  When monitoring custom progress using AJAX it is needed to call  RadProgressManager's StartProgressPolling() javascript method in order to activate the process of monitoring the progress.
  
  
  
  There is no need to set a query string parameter with key RadUrid in the code behind when using AJAX for monitoring a progress.
  
  
  
  
  For the normal functioning of RadProgressManager and RadProgressArea with RadMemoryOptimization the page's URL should contain a query string parameter with key RadUrid. When using AJAX for monitoring the custom progress instead of making postback  this query string parameter should be set in the code behind.
  
  The examples demonstrating the above suggested solution are attached.
  
  Note: For Telerik.Web.UI versions 2009.2.826+ use the following code:
  
  

  protected void Page_Load(object sender, EventArgs e)

     {

         if (!IsPostBack)

         {

             //Do not display SelectedFilesCount progress indicator.

             RadProgressArea1.ProgressIndicators &= ~ProgressIndicators.SelectedFilesCount;

   

             RadProgressArea1.Localization.UploadedFiles = "Processed ";

             RadProgressArea1.Localization.TotalFiles = "";

             RadProgressArea1.Localization.CurrentFileName = "File: ";

   

             RadProgressContext progress = RadProgressContext.Current;

             //Prevent the secondary progress from appearing when the file is uploaded (FileCount etc.)

             progress["SecondaryTotal"] = "0";

             progress["SecondaryValue"] = "0";

             progress["SecondaryPercent"] = "0";

         }

   

     }

  Update (reply not available anymore): Even if you remove getRadProgressManager().startProgressPolling() from AjaxMananger OnRequestStart and add it to the Button1 OnClientClick event, the progress area will show for both buttons.
  
  This sample is not complete or it's not working with the latest updates. I tried to use it but it's showing the progress area for any post back event not only for the Button1. To reproduce the error just add a new Button and add the AjaxManagerSetting as follows. The progress area will show for both buttons even if the startProgress is wired up only to the first one.
  
  <AjaxSettings>
              <telerik:AjaxSetting AjaxControlID="SubmitButton">
                  <UpdatedControls>
                      <telerik:AjaxUpdatedControl ControlID="Label1" />
                  </UpdatedControls>
              </telerik:AjaxSetting>
              <telerik:AjaxSetting AjaxControlID="SubmitButton2">
                  <UpdatedControls>
                      <telerik:AjaxUpdatedControl ControlID="Label1" />
                  </UpdatedControls>
              </telerik:AjaxSetting>
          </AjaxSettings>
  
  In code behind addd
  
  protected void Button2_Click(object sender, EventArgs e)
          {
              System.Threading.Thread.Sleep(3000);
              Label1.Text = "Updated by Button2";
          }

  Hello Tony,
  
  This is a normal behavior since the Progress Area is shown on every Request-Start.
  
  You need to check which button was clicked before you call the startProgressPolling() method.
  
  All the best,
