Chapter 1: AJAX Technologies

❑ Control architecture: Every server control goes through a set of steps or phases collectively

known as the control lifecycle, and raises events before and/or after each lifecycle phase to

allow you to customize the control lifecycle.

❑ Declarative programming: The ASP.NET declarative programming enables you to program

declaratively without writing a single line of imperative code. The ASP.NET runtime

automatically parses the declarative code, dynamically generates the associated imperative

code, dynamically compiles the imperative code, caches the compiled imperative code for

future use, and instantiates and initializes the associated compiled .NET types.

Thanks to ASP.NET and the .NET Framework, the server-side Web application development world can

take full advantage of these important programming benefits to enormously boost productivity and to

write more reliable and architecturally sound programs.

As you’ll see throughout this book, the ASP.NET AJAX framework provides similar programming

benefits to developers of AJAX-enabled Web applications. The ASP.NET AJAX Framework consists of

two frameworks: the ASP.NET AJAX client-side framework and the ASP.NET AJAX server-side frame-

work. The ASP.NET AJAX server-side framework is an extension of the ASP.NET Framework, which

provides all the server-side support that an AJAX-enabled Web application needs.

Installing the ASP.NET AJAX Extensions

and ASP.NET Futures

Make sure both the ASP.NET AJAX Extensions and ASP.NET Futures are installed on your computer.

You can download free copies of the ASP.NET AJAX Extensions and ASP.NET Futures from the official

Microsoft ASP.NET AJAX site at

Summary

This chapter first discussed the main AJAX technologies. Then it provided a brief description of the ASP.

NET AJAX framework. As mentioned, the ASP.NET AJAX framework consists of two main frameworks:

the ASP.NET AJAX client-side framework and ASP.NET AJAX server-side framework.

The next chapter begins your journey of the ASP.NET AJAX client-side framework, where you’ll learn a

great deal about the ASP.NET AJAX JavaScript base type extensions.
