Validating a checkbox in asp net c

The bad thing about server-side validation is that it requires trips back and forth to the server.

This takes a lot of resources and makes for a slower-paced form for the user.

Some sites on the Internet don't carry this inputted information back to the form page, and the user is then required to enter all the information into the form a second time.

Obviously, this may cause people to leave your site for another.

Validation server controls are a series of controls that help you validate the data that the user enters into the other controls that are provided with ASP. They determine whether the form can be processed based upon the rules that you define in the validation server controls.
