PageRequestManagerParserErrorException Issue with Export Button
Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed
In IE 10 from an ImageButton that initiated an Export (Response.Write to output stream) from within an UpdatePanel.
Give the ImageButton a unique ID if it didn't had one (mine was blank as control was auto-generated)
Flag the button as using normal postback instead of rendering in update panel:
ScriptManager scriptManager = ScriptManager.GetCurrent(this.Page);
if (scriptManager != null)
