Hi, guys, I got a problem which made me crazy:
When I return back to a page which stayed for a long time and type a value into a textbox and click a button, I got an error, displaying "Error on page" and the detailed info is :
Message: Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 500
Could anybody meet this before and tell me how to fix it?
