4.2 Validation Controls

One of the generally universal elements of Web pages is a form in which the users can payment
data that is posted back to the server. These forms are made up of different types of HTML
elements that are constructed using straight HTML, HTML server controls, or Web server controls.
A variety of HTML elements, such as text boxes, check boxes, radio buttons, drop-down lists
and more can be used in forms.
Often when our ASP.NET applications are collecting information from a user, we want to ensure
that the data that we collect is valid. Some users are not interested in spending enough time
to enter the correct information into a form, and in some cases, users might even intentionally
enter false information to gain access or get past a certain step in our application’s workflow
