Book Description

Get an expert introduction to the new JavaScript enhancements (code-named â??Atlasâ?) for Microsoft ASP.NET 2.0. More than a basic AJAX (Asynchronous JavaScript And XML) script library, the Microsoft implementation brings object orientation to JavaScript, together with enhanced client-side and server-side controls that greatly simplify coding while delivering enhanced Web experiences with any browser. Scheduled for release with the next version of Microsoft Visual Studio®, code named â??Orcas,â? AJAX extensions and tools can be used by developers today. This book offers expert insights direct from the Microsoft product team and noted ASP authority Dino Esposito, as well as hands-on instruction and examples of Web development with AJAX. This ideal reference will be updated online until the final release, keeping readers up to date with the evolving tool. The book includes code samples in ASP.NET 2.0 created using C#and JavaScript.
