Re: Invalid postback or callback argument

Kulermaster

As you guess i want to avoid the EnableEventValidation="false" ...

Actually i wonder why this exception is thrown at all.

I have a master page with two LinkButton controls on it. One is for EN and another for FR language. I removed all the code from the click events but the exception kept throwing. 

Any ideas?

Thank you

The error usually means you are changing server controls on the client like adding items to a dropdown then submitting the newly added dropdown item. 

Here's more information on the error.
