I am working in SharePoint 2010 environment. I am using Telerik RadGrid and i have implemented RadGrid drag/drop column to reorder the rows in the grid, when drag/drop event starts i get the following error.
Message: 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 '
<!DOCTYPE html PUB'.
I have RadGrid inside the asp:updatepanel.
