Since AJAX involves many disparate technologies at different layers in the networking stack, implementing AJAX without the use of an AJAX framework is difficult and error-prone. Fortunately, Microsoft has released a free AJAX framework for ASP.NET developers: Microsoft ASP.NET AJAX. This article is the first in a series of articles that examines the ASP.NET AJAX framework. This installment provides an overview of AJAX technologies and looks at getting started with Microsoft's framework. Future installments will focus on specific controls and scenarios..

What developer wants to spend hours manually writing Ajax pluming when the Ajax.NET framework does this for free? The Ajax.NET Framework presents a remarkably easy-to-use framework that will simplify Ajax development and allow developers to spend more time on implementation details and less time on parsing XML.

Over the past several years web developers have started using JavaScript to make asynchronous postbacks to the web server that only transmit and receive the necessary data; these techniques are commonly referred to as AJAX. Microsoft has released a free AJAX framework for ASP.NET developers named Microsoft ASP.NET AJAX. This article series examines using Microsoft's ASP.NET AJAX framework to build responsive user interfaces.

AJAX has made layering contextual information into a Web interface completely elegant and unobtrusive. If you build Web apps, this is one trick you definitely want in your hat. Find out how to exploit the HoverMenuExtender in the ASP.NET AJAX Control.

Highrise and other new AJAX enabled tools have this feature that when you type in a search query, it automatically updates the search results below. It's almost like an auto-complete box, but with the full results on the page instead of a dropdown list below the control. Unfortunately, I didn't find anything like this in the Microsoft ASP.NET AJAX Toolkit. So, I decided that this was a good way to finally dive into the AJAX Control Toolkit..

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.

This article provides an overview of JSONs rules and illustrates how it is used in AJAX-enabled web applications. Well also look at using the Microsoft ASP.NET AJAX framework's JavaScriptSerializer class, which facilitates serializing and deserializing JSON-formatted messages on the client in JavaScript or in C# or Visual Basic code on the server.

This tutorial is intended to explains quickly how to implement Drag and Drop using ASP.NET 2.0 AJAX Futures November CTP.

To explain this technology I've created a simple project with a custom Ajax control that implement a Jigsaw Puzzle Game.
