  I have a grid that I reuse through out the web app.  Since this is the case, I decide to create a user control for the grid.  When I did this, I notice the loading panel no longer appears.  Here's my ajaxmanager code on the page.

  
  

  <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">

      <AjaxSettings>

          <telerik:AjaxSetting AjaxControlID="SearchButton">

              <UpdatedControls>

                  <telerik:AjaxUpdatedControl ControlID="SearchResultsGrid" LoadingPanelID="LoadingPanelUC" />

              </UpdatedControls>

          </telerik:AjaxSetting>

          <telerik:AjaxSetting AjaxControlID="SearchResultsGrid">

              <UpdatedControls>

                  <telerik:AjaxUpdatedControl ControlID="SearchResultsGrid" LoadingPanelID="LoadingPanelUC" />

              </UpdatedControls>

          </telerik:AjaxSetting>

      </AjaxSettings>

  </telerik:RadAjaxManager>

  <telerik:RadAjaxLoadingPanel ID="LoadingPanel1" runat="server">

  </telerik:RadAjaxLoadingPanel>



  
  Here is the usercontrol:       
  

  <div class="grid_12">

      <uc:AccountsGrid runat="server" ID="SearchResultsGrid"/>

  </div>

  
  What am I doing wrong?

  Per this article:
  http://www.telerik.com/help/aspnet/ajax/ajxloadusercontrols.html
  I tried wrapping the user control with a panel and referencing it in the radajaxmanager.  No dice.  Thanks again for any help.

  Hi Travis,
  
  

  Could you please let me know if the RadAjax LoadingPanel has skin set to it? Also please try to show and hide the loading panel explicitly using the following help topic.

  Loading panel has no skin and is set like the code above shows.
  
  I'll take a look again at this article, but didn't want to have to go this route as I'll have to implement this on every page that has this grid (user control).. which somewhat defeats the purpose of the user control.

  Hello Travis,
  
  Try to set Skin="Default" for the RadAjaxLoadingPanel and verify if this makes any difference.
  Also note that ion this scenario it will not be necessary top set it in each UserControl but you could add this script in the main page where the main RadAjaxManager is laced and use its client events.

  Well, I tried both suggestions.  Neither work for me.  Any other ideas?
  
  Should have anything special within the user control?

  Hi Travis,
  
  

  Please try to wrap the UserControl into always visible asp Panel and add this panel into the RadAjaxManager settings instead of the UserControl itself. Let me know if this helps.

  I did something like the below so that I could control the placement of the panel.  When I did this, I was able to position it on the page in such a way that I wanted (and it WAS visible).  Thanks!
  
  

  <telerik:RadAjaxLoadingPanel ID="SearchLoadingPanel" runat="server" SkinID="crawler"  IsSticky="true" 

      Style="top: 160px; left: 400px; position: absolute; z-index:99999;">

      <uc:LoadingPanel ID="LoadingPanelUC" runat="server" />

  </telerik:RadAjaxLoadingPanel>
