ASP.Net 2.0
ASP.Net 2.0 significantly enhances the scripting model to incorporate this methodology. They call it script callbacks instead of Ajax. It works essentially the same as I described earlier, but ASP.Net 2.0 takes it a step further by providing tools and support. For a comprehensive explanation of script callbacks in ASP.Net 2.0, take a look at this article: http://msdn.microsoft.com/msdnmag/issues/04/08/CuttingEdge/.
Considerations
1. Ajax blurs the line between correct tiering techniques since much of the work has been moved to the client. Consideration should be given when designing such applications using an emerging methodology. The client (browser) is doing more of the processing work, and the JavaScript to accomplish this is fairly complex. It's handling keystrokes, mouse clicks, interaction with the DOM, processing of these events, and data coordination with the server.
2. It should also be noted that many users might not want to run JavaScript on their browsers. Your Web site audience is a consideration.
3. The name Ajax is not official. The folks at Adaptive Path are given credit for this catchy name. In ASP.Net 2.0, it is referred to as "script callbacks."
