Adding AJAX and Client Capabilities Roadmap

You can enhance the server-based features of ASP.NET by including client-script functionality in ASP.NET Web pages. You can use client script to provide a richer, more responsive user interface to users. You can also use client script to make asynchronous calls to the Web server while a page is running in the browser.

ASP.NET provides two approaches for including client capabilities. The first approach is to use the AJAX features of ASP.NET. ASP.NET AJAX includes a library of client script functions that bring many of the advantages of object-oriented programming and of the ASP.NET model to client scripting. ASP.NET AJAX also provides server-based support that includes Web server controls that can automatically render client script that is required for AJAX functionality.

The second approach is to create client script and integrate it yourself into ASP.NET Web pages. This approach is useful if you have only small pieces of client script or if you want to integrate existing client script into your application. This approach is used by many ASP.NET Web server controls (for example, the validator controls) to add client functionality.
