Hi,
I have to show a progress indicator while the excel workbook is being created. The excel workbook creation takes anywhere between 1-3 mins. I would appreciate if Syncfusion could guide me implement this!
I have uploaded a small sample that works without the ajax UpdateProgess control.
I keep getting this message with the UpdateProgress control -
"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."
Thanks!
