This is the first comprehensive, code-rich guide to custom ASP.NET AJAX server controls for experienced ASP.NET developers. Unlike other books on ASP.NET AJAX, this book focuses solely on server control development and reflects the significant improvements in ASP.NET 3.5 AJAX and the latest Visual Studio 2008 features for streamlining AJAX development   Adam Calderon and Joel Rumerman first review the core Microsoft AJAX Library and JavaScript techniques needed to support a rich client-side experience. Next, they build upon these techniques showing how to create distributable AJAX-enabled controls that include rich browser-independent JavaScript client-side functionality. The authors thoroughly explain both the JavaScript and .NET aspects of control development and how these two distinct environments come together to provide a foundation for building a rich user experience using ASP.NET AJAX.   Create object-oriented cross-browser JavaScript that supports .NET style classes, interfaces, inheritance, and method overloading Work with components, behaviors, and controls, and learn how they relate to DOM elements Learn Sys.Application and the part it plays in object creation, initialization, and events in the Microsoft AJAX Library Build Extender and Script controls that provide integrated script generation for their corresponding client-side counterparts Localize ASP.NET AJAX controls including client script Discover ASP.NET AJAX client and server communication architecture and the new support for Windows Communication Foundation (WCF) Understand ASP.NET AJAX Application Services Create custom Application Services Design controls for a partial postback environment Understand the AJAX Control Toolkit architecture and the many features it provides Develop highly interactive controls using the AJAX Control Toolkit Understand AJAX Control Toolkit architecture and build controls that utilize the toolkit   Foreword xxv Preface xxvii Acknowledgments xxxv About the Authors xxxix   Part I: Client Code Chapter 1: Programming with JavaScript 3 Chapter 2: Microsoft AJAX Library Programming 51 Part II: Controls Chapter 3: Components 121 Chapter 4: Sys.Application 169 Chapter 5: Adding Client Capabilities to Server Controls 207 Chapter 6: ASP.NET AJAX Localization 255 Chapter 7: Control Development in a Partial Postback Environment 317 Part III: Communication Chapter 8: ASP.NET AJAX Communication Architecture 371 Chapter 9: Application Services 425 Part IV: AJAX Control Toolkit Chapter 10: ASP.NET AJAX Control Toolkit Architecture 481 Chapter 11: Adding Client Capabilities to Server Controls Using the ASP.NET AJAX Control Toolkit 513 Appendixes Appendix A: JavaScript in Visual Studio 2008 547 Appendix B: Validating Method Parameters 555 Appendix C: ASP.NET Handlers and Modules 559 Appendix D: Client Error Handling Code 569   Index 577
