I am following the example in "Handling Time Zones" in the documentation for RadScheduler to use JavaScript and asynchronous AJAX requests to discover the time zone on the client. I copied the following block of code into my ASP page (see the code below).
But when I compile, I always get an error saying, "The name 'RadAjaxManager1' does not exist in the current context ".
I do have the RadAjaxManager in the ASP page and its ID is "RadAjaxManager1".  And I have RadAjaxLoadingPanel in my code, too. I tried to put the block of code in different location of the ASP page, but it did not help.
Also, if I removed reference to "RadAjaxManager1" in the following block of code, I would get another error on ajaxPanel.Show, saying "the object does not support the method".

What did I do wrong?

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">
 
<script type="text/javascript">
   
var syncComplete = false;   
   function SynchronizeClientTimeZoneOffset()
   {
     if (!syncComplete)
     {
       var ajaxPanel =
<%= RadAjaxLoadingPanel1.ClientID %>;
       var schedulerId = '
<%= RadScheduler1.ClientID %>';
       ajaxPanel.Show(schedulerId);     
       var now = new Date();
       var offset = now.getTimezoneOffset()
       InitiateAsyncRequest(-offset);     
       ajaxPanel.Hide(schedulerId);     
       syncComplete = true;
     }
   }   
   function InitiateAsyncRequest(argument)
   {
      var ajaxManager =
<%= RadAjaxManager1.ClientID %>;
      ajaxManager.AjaxRequest(argument);
   }
   
   Sys.Application.add_load(SynchronizeClientTimeZoneOffset);
  
</script>       
</telerik:RadCodeBlock>
