Interestingly enough, the technol- ogy pillars of what we know today as AJAX (Asynchronous JavaScript and XML) were already in place at that time. It wasn’t until the advent of a few mainstream applications, such as Google Maps, that people started to realize the potential of these AJAX apps. In recent years, there has been a huge rise in the popularity and demand for AJAX and as such, a number of frameworks have been intro- duced to the marketplace to ease the traditionally difficult development effort associated with creating AJAX apps. Microsoft, for its part, introduced the ASP.NET AJAX framework, which is a comprehensive package of technologies addressing both client-side and serv- er-side development in addition to a suite of user interface controls (the AJAX Control Toolkit). This brought major productivity gains to AJAX development in the ASP.NET world. Its broad spectrum of features and controls, wide commu- nity support, and tight integration with Visual Studio has made ASP.NET AJAX an excellent choice for implementing AJAX applications within ASP.NET and even more so for enhancing existing ASP.NET applications. This book is a primer to this technology. It introduces you to ASP.NET AJAX, explores its main features and controls, and walks you through how to build AJAX applications quickly and easily through a series of practical examples that demonstrate the most powerful features of the technology. If you are just start- ing out in the world of ASP.NET AJAX, this is the book you need.
