An Introduction to AJAX and Atlas with ASP.NET 2.0
Traditionally, web applications have left a lot to be desired from a user experience standpoint, due primarily to the "request/response" lifecycle. Any interaction with a page typically requires a postback to the web server (a "request"), which then performs any server-side tasks needed and returns the updated page's markup (the "response"). Outside of intranet-based applications, such behavior adds a bit of a lag when interacting with a page. One approach to improving the end user's experience is to use AJAX. AJAX is a technique for using JavaScript and the XMLHttpRequest object to make light-weight HTTP requests back to the web server from client-side script. Once a response is received, the web page's layout can be seamlessly refreshed using JavaScript to message the page's Document Object Model (DOM) and CSS settings. AJAX-enabled pages provide a slick, responsive user experience, making web-based applications function more like desktop-based ones.
In the past adding AJAX type behaviors to your web application was difficult and came with a steep learning curve since AJAX encompasses a bevy of technologies (JavaScript, XML, XmlHttpObject, HTTP requests, DHTML, and so on). With the advent of the ASP.NET Atlas framework, however, there is much less of a reason to feel so overwhelmed when it comes to AJAX!

Accessing Server-Side Data from Client Script: Using WCF Services with jQuery and the ASP.NET Ajax Library
Today's websites commonly exchange information between the browser and the web server using Ajax techniques - the browser executes JavaScript code typically in response to the page loading or some user action. This JavaScript makes an asynchronous HTTP request to the server. which then processes the request and, perhaps, returns data that the browser can then seamlessly integrate into the web page. Two earlier articles - Accessing JSON Data From an ASP.NET Page Using jQuery and Using Ajax Web Services, Script References, and jQuery, looked at using both jQuery and the ASP.NET Ajax Library on the browser to initiate an Ajax request and both ASP.NET pages and Ajax Web Services as the entities on the web server responsible for servicing such Ajax requests.
This article continues our examination of techniques for implementing lightweight Ajax scenarios in an ASP.NET website. Specifically, it examines how to use the Windows Communication Foundation, or WCF, to serve data from the web server and how to use both the ASP.NET Ajax Library and jQuery to consume such services from the client-side.
