Hi, well as the error is already saying, you have to disable event validation or register the events for validation. This is a security feature to disallow illegal postbacks. I'm guessing you are using some kind of dynamic controls within your app. To solve the problem you can: 1.) Open the web.config and add the the tag <pages enableEventValidation="false"/> 2.) or open the page (in VS) causing the error, switch to HTML Layout, browse to the first line and set EnableEventValidation="false" (or add if it is not there) 3.) or use the ClientScriptManager, but I never did this before... 4.) or don't use dynamically created controls :) Regards Sebastian It's not a bug, it's a feature! Check out my CodeProject article Permission-by-aspect. Me in Softwareland.

thankyou..
