  We have designed several User Controls (.ascx) using the new AJAX Extentions for ASP.Net from Microsoft and have encountered a problem when editing a page.  If there's a control on the Page that contains an UpdatePanel and you drop any other control on the page you get an Exception.  The ScriptManager control is on the MasterPage for the Template we are using for this page.  You can easily reproduce this my creating a User Control and dropping an UpdatePanel control on it.  Then add the control to a page.  Next add any additional control to the page and you'll get the error.  This is a serious problem because it prevents us from adding User Controls that contain UpdatePanels to a page, or at best it must be added last.

  Hi Jason,
  
  Thank you very much for turning our attention to this issue. We agree that support for MS Ajax is important issue and we will fix it for the official release of Sitefinity 3.0.

  Hi Jason Grovert,
  
  I was able to test the scenario you are describing with AJAX Extentions for ASP.Net but was not able to reproduce any exceptions. I did the following:
  
  1. Created User Control with UpdatePanel on it.
  2. Added Script Manager to the master page.
  3. Updated my web.config.
  4. Added the control to the page and some other control to the page without any errors.
  
  Can you let me know what exception you get and if there is some inconsistency in my and your steps with using ajax user controls. Perhaps it would be much easier if you could send us some basic project which rises the problem. Thanks in advance. I am looking forward for your reply.
  
  All the best,

  What do you mean by "Updated my web.config"?  We can reproduce the error every time. (see below)

  Hello Jason,
  
  I was able to reproduce your error this time. Sorry for misleading you. Perhaps I tested with an older version. Anyway the problem is already localized and we will give it a closer look. Unfortunately, we cannot give you a quick workaround for it but you could add your control last to the page when you are sure you have finished with the page layout.
  
  Once again I am sorry and thanks for the valuable feedback. Your Telerik points have been updated.
  
  Best wishes,

  Has there been any resolution to this? We have the same problem and it makes sitefinity unusable.

  I applied the SP2 patch, but I still get an exception when I have an UpdatePanel in a MasterPage and try to edit the masterpage, or a page using the masterpage.
  
  To reproduce the problem, do the following:
  
  1. Create a masterpage with both a ScriptManager and an UpdatePanel, and upload it in SiteFinity to generate a Template.
  2. Try to edit the template. You will get an exception, stating that you "Cannot unregister UpdatePanel with ID 'myUpdatePanel' since it was not registered with the ScriptManager. This might occur if the UpdatePanel was removed from the control tree and later added again, which is not supported.
  Parameternaam: updatePanel "
  
  I will try using the RadAjax control and see what happens.
  
  Best regards,
  Sipke

  Using RadAjax solved my problem in this case...

  Is there a resolution to using the UpdatePanel? Is this still being addressed?

  Hello Sipke and Steve,
  
  Thanks a lot for pointing out this issue. It seems that the problem has been fixed for User Controls only, i.e. when you use UpdatePanels in a User Control. For the time being, the workaround is to avoid using UpdatePanels in the master pages.
  You could separate the functionality that should be updated without refreshing the whole page in a User Control and wrap the specific regions inside UpdatePanels.
  
  Your Telerik accounts have been updated for noticing this.

  Hi Sipke, I was wondering if you could help? 
  
  I have been having similar issues with getting update panels to work in Sitefinity.
  You mentioned that:
  
  "Using RadAjax solved my problem in this case..."
  
  Can I ask how you achieved this?  I tried switching to the RadAjax and got same issues.
  
  e.g. when dragging a generic content control into a page I get...
  
  Cannot unregister UpdatePanel with ID 'des4$ctl06$RadAjaxPanel1Panel' since it was not registered with the ScriptManager. This might occur if the UpdatePanel was removed from the control tree and later added again, which is not supported.Parameter name: updatePanel
  
  Thanks for any advice you can give
  
  Chris

  Hi Everyone,
  After some experimentation I have come up with an alternative solution to using Ajax Update panels in Sitefinity. It might not be ideal for everyone but I thought it might be worth sharing.
  
  First I created my UserControl with Ajax Update Panel functionality in the standard way.
  
  Then I created a second UserControl to upload to Sitefinity. This control has nothing but a single PlaceHolder control in the ascx. In the code behind I added the following...
  
  string pageMode = base.Request.QueryString["cmspagemode"];
  
  if (!string.IsNullOrEmpty(pageMode) && (pageMode == "edit" || pageMode == "preview"))
  {
  // we are in Sitefinity's backend
  // you could load in a message or dummy control
  
  }
  else
  {
  
  Control QuickSearchUserControl = LoadControl("~/UserControls/Custom/QuickSearchFrontend.ascx");
  ControlPlaceHolder.Controls.Add(QuickSearchUserControl);
  }
  
  Basically it detects if you are in the Sitefinity backend using the QueryString "cmspagemode". If we are in the backend don't load the control with the Ajax Update Panel (as it causes issues when editing in sitefinity). If we aren’t load the control as normal.
  

  This could easily be extended into a control with a property for the path to the UserControl to load in and maybe a second property for a message to show in when in the backend of Sitefinity. That way it could be reused across a Sitefinity Site and the path / message properties could be set in the Sitefinity UI.

  Hope this is of some use to you
  
  Thanks
  
  Chris

  Hi,
  
  It seems that this issue has still not been fixed in Sitefinity 3.7. I have a user control with an UpdatePanel in it and it throws an exception in edit mode.
  
  

  Cannot unregister UpdatePanel with ID 'UpdatePanel' since it was not registered with the ScriptManager. This might occur if the UpdatePanel was removed from the control tree and later added again, which is not supported.
  Parameter name: updatePanel

  
  Can you suggest an alternative to using UpdatePanel?

  Hi SilverlightShow,
  
  You can take a look at Cannot unregister UpdatePanel with ID KB article. You could use RadAjaxPanel control and get the number of controls inside this panel. Then you have to clear the controls form the holder add the RadAjaxPanel again.
  
  

  RadAjaxPanel _radAjaxPanel = new RadAjaxPanel();

  radAjaxPanel .Width = Unit.Percentage(100);

  Control c = PlaceHolder.Controls[0];

  while (c != null)

  {  

      radAjaxPanel .Controls.Add(c);

      if (PlaceHolder.Controls.Count == 0)

          break;

      c = PlaceHolder.Controls[0];

  }

  PlaceHolder.Controls.Clear();

  PlaceHolder.Controls.Add(_radAjaxPanel );
