Validation and Rich Controls (links to Sample Chapter PDF)
Author:
Matthew MacDonald
This chapter looks at some of the real promise of ASP.NET and the web control model.
First, you’ll learn about ASP.NET’s 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. You’ll learn how to add
these controls to an existing page and use regular expressions, custom validation functions,
and manual validation. And as usual, you’ll peer under the hood to see how
ASP.NET implements these features.
