title: How can I make the Telerik progress bar work?
body: <p>I have a Telerik progress bar in my project: </p>
  
  <pre><code>&lt;telerik:RadProgressManager ID="RadProgressManager" Runat="server" /&gt;
  &lt;telerik:RadProgressArea ID="RadProgressArea" Runat="server"&gt;&lt;/telerik:RadProgressArea&gt;   
  &lt;asp:button id="Button1" runat="server" text="Submit" /&gt;
  </code></pre>
  
  <p>On button click I try to run this method:</p>
  
  <pre><code>private void MethodWhichUpdatesTheProgressContext(UploadedFile file, int countFile)
  {
       const int total = 100;
       RadProgressContext ProgressContex = RadProgressContext.Current;
       ProgressContex.SecondaryTotal = "100";
  
       for (int i = 0; i &lt; total; i++)
       {
           ProgressContex.CurrentOperationText = "Uploading zip file percentage " + i.ToString();                
  
           if (!Response.IsClientConnected)
           {                    
               break;
           }
  
           System.Threading.Thread.Sleep(100);
       }
  }
  </code></pre>
  
  <p>Project builds without any errors but progress doesn't change.
  How do I properly fire the progress bar animation?
  If I put this progress bar on control, it can effect this?</p>
