Chapter 9. Validation

This chapter looks at some of the most useful controls that are included in ASP.NET: the validation controls. These controls take a previously time-consuming and complicated task—verifying user input and reporting errors—and automate it with an elegant, easy-to-use collection of validators. Each validator has its own built-in logic. Some check for missing data, others verify that numbers fall in a predefined range, and so on. In many cases, the validation controls allow you to verify user input without writing a line of code.

In this chapter, you'll learn how to use the validation controls in an ASP.NET web page and how to get the most out of them with sophisticated regular expressions, custom validation functions, and more. ...
