Hello,
In my application I've implemented a search page with 3 instances of a user control using a RadGrid. As the page reloads to Rebind the data (using the search text), I gete the following error.
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page.
I've read quite a few articles about this error and the theory about it I do understand. But I can't seen to figure out how to solve it. I believe the Edit-button (ButtonType = "ImageButton") is causing the error, because it is not yet registered for event validation.
How can I accomplish that each edit button is registered?

I found a solution (finally). A collegue of mine proposed a way to get the databinding out of the PageLoad.
