I have a telephone number user control in which I need to validate the
data entered (Required field validation and regular expression
validation). The phone number is represented as 3 text boxes so I have
3 required field validation and regular expression validation controls.
I set the display property to none and have a validation summary
control in my hosting page. I have a method in the user control that
then assigns the error message and the validation group to these 6
controls. The problem I'm having is that if a user doesn't enter data
in any of the fields they get 3 duplicate error messages. Is there any
way to prevent duplicate messages from showing up in the validation
summary control???
