Validating expression

[John]

Hi

Is it possible to validate a text box to ensure values entered are in the
format 99-99-99? All digits are required.

Thanks

Regards

Yes, use the RegularExpressionValidator and set hte ValidationExpression to
\d{2}\-\d{2}\-\d{2}

there's probably a more efficient way to write that... You'll also want to
put a requiredfieldvalidation to make sure atlast something is entered
(regularexpressionvalidator won't fire if the field is blank).
