Explain the Validation Controls used in ASP.NET 2.0?

Validation controls allows you to validate a control against a set of rules. There are 6 different validation controls used in ASP.NET 2.0.

RequiredFieldValidator – Checks if the control is not empty when the form is submitted.

CompareValidator – Compares the value of one control to another using a comparison operator (equal, less than, greater than etc).

RangeValidator – Checks whether a value falls within a given range of number, date or string.

RegularExpressionValidator – Confirms that the value of a control matches a pattern defined by a regular expression. Eg: Email validation.

CustomValidator – Calls your own custom validation logic to perform validations that cannot be handled by the built in validators.

ValidationSummary – Show a summary of errors raised by each control on the page on a specific spot or in a message box.
