How to use RegularExpressionValidator instead of RequiredFieldValidator

[Peter]

Hi All,

I would want to use RegularExpressionValidator instead of
RequiredFieldValidator. I coded ValidationExpression="^[a-
zA-Z0-9 ]+$">. But it doesn't work. Do you have any idea?

Thanks,

Peter

A regular expression validator only fires if there are contents in the
control. If you need to validate against an expression, and you additional
require that the user inputs something, then you need to use both validator
controls.
