Hi,

I have a textbox in which two expressions are valid.

999-99-9999

99-9999999

How can i use regular expression validator for this.

I don't want to use javascript to validate this because i am using requierd field validator for other fields which i am showing in validation summary.

Please suggest,

Thanks,

Saurabh

You would use a RegularExpressionValidator with the regular expression in the ValidationExpression property.  The regular expression syntax should be the same.

These sites should help if you are not sure on the regular expression to use...
