ASP.NET 2.0 represents a significant upgrade from its predecessor. Along with 50 code-reducing controls, ASP.NET 2.0 offers a simper data-binding model, membership and role services for greater application security, master pages and themes for faster design and a variety of navigation improvements.
Steven Walther's ASP.NET 2.0 Unleashed is a revision of his previous work for the initial ASP.NET. This new reference checks in at nearly 2,000 pages and is divided into 10 sections, which cover topics such as data access, components, security and Web parts. The final chapter shows readers how to build a sample e-commerce application.
In Chapter 3, Using the Validation Controls, Walther provides an overview of ASP.NET 2.0's six out-of-the-box controls -- RequiredField, Range, Compare, RegularExpression, Custom and ValidationSummary. That is followed with a tutorial on creating custom controls. Both VB and C# sample code is provided.
