Regular Expression Validator:
In my previous posts, I have covered about 3 types of
validators. In some situations the above 3 validators are helpful till some
extend. Such that they may provide the flexibility to cover basic validation
functionality. Regular Expression validator provide a step ahead functionality.
For example if you want to validate to check the text box, to accept a valid
Email address or phone no in a particular format at these times Regular
Expression validator comes to picture.
