This Wrox Blox will teach you how to create and customize ASP.NET 4 AJAX Preview 4 Client Templates. The author shows you how to use declarative as well as imperative data-binding techniques to address the simple to advanced UI requirements. He also covers how the observer pattern is fully implemented in ASP.NET 4 AJAX and, when used in conjunction with the Client Template markup extensions, provides a developer experience much like XAML-based applications like WPF and Silverlight. This Wrox Blox walks you through how to implement examples that fetch data from ASP.NET Web Forms using Page Methods and ASP.NET MVC controller actions, as well as interfacing directly with ADO.NET Data Services.
