Validator not being validated unless called individually

[Nathan Sokalski]

I have a UserControl, one property of which I have added the
ValidationPropertyAttribute to. The Validator I am using with this
UserControl (which is a RequiredFieldValidator) is not executed on a
postback, and not even if I call this.Validate(MyValidationGroup). However,
if I call MyValidator.Validate(), it validates exactly as I want. I have
included the ValidationGroup property in the RequiredFieldValidator, so I
know that is not the problem. Why is this one validator being singled out?
Thanks.
