Ajax has the power to revolutionize the way web-based applications are designed. This book provides you with a thorough working knowledge of what Ajax has to offer and how to take full advantage of it in your application development.

Following an exploration of how Ajax works with .NET, you'll get acquainted with DHTML, the role of JavaScript and the Document Object Model, and the XMLHttpRequest Object, which is the foundation of Ajax. Then you will examine the Ajax-type features built into ASP.NET and explore the Ajax.NET Professional Library in detail. Finally, you will explore client scripting as well as building and using controls with Microsoft's Atlas. With an entire chapter devoted to debugging, you will have all you need to use this cutting-edge technology.

What you will learn from this book
* What you can do with the open source Ajax.NET Professional Library
* How to use the corresponding functionality, Asynchronous Client Script Callbacks, that comes with ASP.NET 2.0
* Techniques for using the XMLHttpRequest Object to communicate between the client web browser and the server
* An overview of XML, XSLT, and other ways to send data between client and server
* How to integrate Microsoft's Atlas with many of the services available in ASP.NET 2.0

Who this book is for

This book is for programmers who use ASP.NET and are just starting to use Ajax technologies to create more responsive, modern applications.

Wrox Beginning guides are crafted to make learning programming languages and technologies easier than you think, providing a structured, tutorial format that will guide you through all the techniques involved.

Author Notes

Wallace B. "Wally" McClure graduated from the Georgia Institute of Technology in 1990 with a Bachelor of Science degree in electrical engineering. He continued his education there, receiving a master's degree in the same field in 1991. Since that time, he has done consulting and development for such organizations as The United States Department of Education, Coca-Cola, Bechtel National, Magnatron, and Lucent Technologies, among others. Products and services have included work with ASP, ADO, XML, and SQL Server, as well as numerous applications in the Microsoft .NET Framework. Wally has been working with the .NET Framework since the summer of 2000. Wally McClure specializes in building applications that have large numbers of users and large amounts of data. He is a Microsoft MVP and an ASPInsider, and a partner in Scalable Development, Inc. You can read Wally's blog at http://weblogs.asp.net/wallym.
Wally and coauthor Paul Glavich also co-host the ASP.NET Podcast. You can listen to it at www.aspnetpodcast.com. In addition, Wally travels around the southeast United States doing user group talks and sessions at various CodeCamps.
When not working or playing with technology, Wally tries to spend time with his wife Ronda and their two children, Kirsten and Bradley. Occasionally, Wally plays golf and on July 30, 2005, broke par on a real golf course for the first time in his life. If he hadn't been there, he would not have believed it.

Scott Cate is the President of myKB.com, Inc., in Scottsdale, Arizona. myKB.com, Inc., is a technology company specializing in commercial ASP.NET applications. His product line includes myKB.com (knowledge base software), kbAlertz.com (Microsoft knowledge base notifications), and EasySearchASP.net (a pluggable search engine for ASP.NET sites). Scott also runs AZGroups.com (Arizona .NET user groups), one of the largest and most active user group communities in the country, and is a member of ASPInsiders.com, a group devoted to giving early feedback to the Microsoft ASP.NET team. In addition, Scott has coauthored the novel Surveillance , which can be found at http://surveillance-the-novel.com.

Paul Glavich is currently an ASP.NET MVP and works as a senior technical consultant for Readify. He has over 15 years of industry experience ranging from PICK, C, C++, Delphi, and Visual Basic 3/4/5/6 to his current specialty in .NET C++ with C#, COM+, and ASP.NET. Paul has been developing in .NET technologies since .NET was first in beta and was technical architect for one of the world's first Internet banking solutions using .NET technology. Paul can be seen on various .NET related newsgroups, has presented at the Sydney .NET user group (www.sdnug.org) and is also a board member of ASPInsiders (www.aspinsiders.com). He has also written some technical articles that can be seen on community sites, such as ASPAlliance.com (www.aspalliance.com).
On a more personal note, Paul is married with three children and two grandkids, and holds a third degree black belt in budo-jitsu.

Craig Shoemaker can't sit still. As the host of the Polymorphic Podcast (polymorphicpodcast.com), Craig teaches on topics as timely as software architecture and as cutting edge as the latest Ajax technologies. Whether he's writing for CoDe Magazine , ASPAlliance, or DotNetJunkies or speaking at local user groups, Southern California Code Camp, or VSLive!, Craig loves to share his passion for the art and science for software development. Craig is also a full-time software engineer for Microsoft Certified Partner PDSA, Inc. (pdsa.com) in Tustin, California.
