The validation control classes are inherited from the Base Validator class hence they inherit its properties and methods.Therefore, it would help to take a look at the properties and the methods of this base class, which are common for all the validation controls: The Regular Expression Validator allows validating the input text by matching against a pattern of a regular expression.The following two mutually inclusive properties list out the error message: Complex pages have different groups of information provided in different panels.In such situation, a need might arise for performing validation separately for separate group.provides the developer with different types of validation controls.One most important point to note is that the validation is done on the client side as well as on the server side.

These expressions can be phone number, email address, zip code and many more. Simply set the Validation Expression property to any type of expression you want and it will validate it.
