Ajax Technology : Rich Internet Application

At present  Ajax,  a"Rich Internet Application" is a common term . Majority of us are also aware that it is not a technology but application of several technologies that enables greater usability and responsiveness of browser-based applications plus its benefits include zero-installation and extremely low maintenance of Web development.
Before we begin with AJAX we need to download the AJAX framework and install it to our system in order to  create a  AJAX web project. Within in few minutes we can download AJAX framework and create an AJAX enabled web site in Visual Studio 2005 utilizing C#.

First of all we need to install the "ASP.NET AJAX Extensions 1.0" and the "ASP.NET AJAX Control Toolkit". Now simply click on the "AJAX" link to get to the home page for AJAX. Once you are on the home page click on the "Downloads" link to get to the ASP.NET AJAX Control Toolkit.

After downloading it  you are geared to experience the instant website development that enables you to kick away the  CTRL + R. Most of you might be knowing it but for those who have joined the "techno geeks" recently, Ajax have trimmed the need to click CTRL + R to refresh a page. Instead,  pages with Ajax elements refresh automatically. Even on the regular pages. If you fill out forms you have to click the "Submit" button before anything happens. No doubts few website with Ajax still use submit buttons, majority of these pages can simply update parts of the page instantly, giving users an immediate response to their inputs.

This allows users to react right away to the errors or information displayed. This is very helpful, as when you as a user select a desired user name, websites designed on Ajax  show users right away if the desired user name is available. By doing so, you don't have to wait until they submit the entire form before they find out that the user name you want is accepted.
