This tutorial will explain how to correctly use the Validation server controls built into the .NET Framework to validate user input on your pages. We begin by defining what validation is and the differences between client side and server side validation. Complete working examples of each of the validation controls are provided as well as solutions to some of the common problems that arise when using the Validator controls, including how to implement validation groups. These can be used for submitting different sets of validated fields separate from other sets of validated fields whilst only validating the set of fields being submitted.
