Microsoft's ASP.NET technology is a popular and enduring technology that can be expanded with custom server controls. Custom server controls allow programmers to add advanced features to their web sites by extending existing, well-known controls such as text boxes and buttons. This book covers how to work with custom server controls and how to add AJAX functions into these applications with Microsoft's implementation of AJAX, ASP.NET AJAX (formerly Atlas). ASP.NET AJAX is the de facto standard for implementing Ajax in ASP.NET 2.0 applications, and every ASP.NET 2.0 developer has to bear it in mind when creating a cutting-edge application. The intended reader is an experienced ASP.NET developer who wants to get the most out of server controls and add Ajax development to their suite of skills. No other book on server controls covers ASP.NET AJAX, so developers interested in this hot topic have to buy this book. Uniquely, it integrates client-side development technologies such as DHTML and JavaScript with server control technology, which is essential in a modern web application.
