Greetings.

I have a webform with a grid control. I have enabled paging and when I click on page 2, I receive 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. 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.


I have tried putting the enableEventValidation in the page directive as well as web.config and still receive the same error. I also have another page with a grid control and the paging seems to work fine on it.

Any ideas are greatly appreciated.

Rhonda
