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
Any idea what the cause may be?
