1. Is it possible to have more than one Validator for a single ASP.Net Server Control?
You can include multiple validators on one control. For instance, let's say you have a TextBox for users to enter an email address. First off, you want it to be required, so you use a RequiredFieldValidator. But, also, you want to make sure you have an email address that is in the correct 'email' format.
2. Therefore, you can include a RegularExpressionValidator to validate the input, to make sure it is in the correct format, before it's submitted via the form. In both instances, the ControlToValidate can be the SAME TextBox - no problem!
