In the RequiredFieldValidator, is the ControlToValidate property set to an
existing control? Is the control that ControlToValidate refers to inside a
Template (things can be a little tricky when validating controls inside
Templates)? Does the RequiredFieldValidator work if you set
EnableClientScript=False (this will help you determine whether it is a
client-side or server-side problem)? Does the RequiredFieldValidator work if
you have it validate a different control on the Page? Check each of these
and see if it helps determine what is causing the problem.
