Invalid postback or callback argument
-
am using asp.net 1.1 to code the web page and my virtual directory is pointed to use asp.net 2.0 calss library (client requirement) Can any one help me with the following error that am getting "Invalid postback or callback argument. Event validation is enabled using in configuration or in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation."

Krishna, how did you implement ICallbackEventHandler for 2.0? Can you post your code? I can help you if I see your code first.
