I have the CustomValidator's Text property set to *. When checking one of the two radio buttons that fire the validation, it puts the cursor in the textbox and shows the * as expected. However, when I enter a valid value into the textbox and move on to another control on the form, the * stays (submitting the form does work even though * is still there; may be confusing for users).
Compare this behavior to say the RequriedFieldValidator on a textbox. When the validated textbox is empty and it loses focus the * immediately appears and the focus stays on the textbox. But when a valid value is entered and focus is moved to another form control, the * disappears. How can I make my CustomValidator remove the * after a valid value is entered?
