Actually, that's all we need to test the most basic part of the Required Field Validator. Validation is only performed serverside if necessary!I'm sure that all the attributes of the controls makes sense by now, so I won't go into details about them.

But then again - there's no real instance of the class being loaded at that moment is there?
