  I'm getting the following error when trying to export data from the scheduler; this was working, I don't know what happened?  I copied the code from what you had on your example site directly: http://demos.telerik.com/aspnet-ajax/Scheduler/Examples/Export/DefaultCS.aspx
  
  The difference is that this control is an updated control (in an AJAX setting) whenever another control is updated...
  
  Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.
  Details: Error parsing near 'BEGIN:VCALENDAR
  VER'.
  
  Any idea what the cause may be?
  
  Thanks.

  Hello Brian Mains,
  
  This error indicates that ajax is being made when the user clicks the export button instead of postback. Please check whether your are calling the Export function
  
  <script type="text/javascript">
 function Export(sender, e)
 {
     $find("<%= RadAjaxManager1.ClientID %>").__doPostBack(sender.name, "");
 }
</script>

  Hey,
  
  That did work; I didn't see the JavaScript.
  
  Thanks.

  I am receiving the same error but my RadAjaxManager is on my Master Page.  How do I call the Manager from my Source page so that the code will work properly?

  Hi Kyle,
  
  Add an AJAX Manager Proxy to your source page and use it the same way you would use RadAjaxManager.

  Hello, I am trying to perform the same thing with the difference that i have my scheduler on a "ascx" user control which i then call on a page that has a master page. I am keep getting that error. I have already a RadManagerProxy on the page but how can i use it from the control "ascx"? Is there another way to set enableAjax = false when exporting to iCalendar?
  
  Thank you in advance.

  Hello Sotir,
  
  You can find the client object of RadAjaxManager in the user control with the following code -
  
  $find("<%= RadAjaxManager.GetCurrent(Page).ClientID %>")
  
  The rest of the implementation would be the same as with the iCalendar export demo.
