Hi poornima,

Is Ajax is a scripting language similar to JavaScript? Did we want to install it seperately? If then how? Is it a free or opensource software?

Hi,
AJAX is not a new programming language, but a new way to use existing standards.AJAX->Asynchronous JAvaScript and XMLAJAX is based on JavaScript and HTTP requests.It have set of tags like we use in html.It is very interesting.It is mostly used for doing client side programming with out hitting the server request much...AJAX is a browser technology independent of web server software and it is platform independent..yes,it is a free open source software.For further details refer W3Schools Online Web Tutorials.

Hi Kirubananth,
I forget to tell u tat you must install AJAX separately.AjaxControlToolKit.dll should be used as a reference in asp.net.Use register tag like this <%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="ajaxToolkit" %> in the page where u r using ajax controls or simply include this line in master page...You must add the namespace for ajax in web.config...

How is ASP.NET AJAX used in this project?
It is an N-tier application, with a user interface (UI) layer, a business layer, and a data access layer. I have used ASP.NET AJAX to implement the UI layer of the portal application which includes the homepage and the widgets’ UI. ASP.NET AJAX provides the framework for loading widgets onto the Start page, updating widgets without doing any postbacks (via UpdatePanel), and changing page layout by dragging and dropping widgets on the page. It also provides a rich collection of Control Extenders, that add cool effects like fade in/fade out, smooth transitions, and client side animations . You can add to the rich client-side experience by providing auto-completion behavior on text boxes, asynchronous data loading via webservice calls, and client-side paging, sorting and many more.
