Anyone have any success with using the EntityDropDownList's RequiredFieldValidator with the AJAX ValidatorCallout control?
I suppose I could just set Required=False and then add a RFV with a ValidatorCallout manually, but I'm wondering if there would be a way to add the Ajax ValidatorCallout to the class, without messing up things for people who do not have the Ajax Control Toolkit installed.
I'm outside ur box, shiftin' ur paradigm.
