I have a webpage that I going to use Ajax and the ScriptManager but whenever I change the
AutoEventWireup=true and have CodeBehind, it gives this error:
"Sys.WebForms.PageRequestManagerServerRoorException: An unknown error occured while processing the request on the server. The status code returned from the server was: 12030."
However, when I change the AutoEventWireup=false and put the code directly on the aspx page, it works OK.
Is there a way to avoid this error and will have the ability to use the Code Behind page?
