The RegularExpressionValidator is a type of
validation control that compares an input control against a pattern
specified in the ValidationExpression. Regular
expression validation is ideally suited for verifying predictable
sequences of characters, such as those in social security numbers,
email addresses, telephone numbers, and postal codes. Validation will
succeed if the input control is empty, unless you also use a
RequiredFieldValidator control. In this way, the
RegularExpressionValidator control works
identically to the
System.Web.UI.WebControls.RegularExpressionValidator
control for full-fledged web pages (although it
won't render client-side validation code).
