The Regular Expression Validator checks whether the value of an input control matches a pattern defined by a regular expression. This type of validation allows you to check for predictable sequences of characters, such as those in social security numbers, e-mail addresses, telephone numbers, and postal codes. The Regular Expression Validator does not require that a field contain a value, it only validates if a value is present.
The use of Regular Expressions it beyond the scope of this User Guide, however there are many resources on the Internet to help learn how to create Regular Expressions for use in this Validator. Form Master provides 4 built-in expressions which are: - E-Mail Address
- Internet URL
- U. S. Phone Number
- U. S. SSN
- U. S. or Canadian Postal Code
