Microsoft Ajax Library

Hi Vipendra,

The Microsoft Ajax Library is a JavaScript library that provides the features for the client portion of the ASP.NET AJAX framework.

• Components. The library provides an infrastructure to build either visual or non-visual JavaScript components. A global JavaScript object – Sys.Application – is responsible for managing the lifecycle of client components.
• JavaScript extensions – An enhanced type system is introduced to emulate object-oriented constructs such as namespaces, classes and interfaces; and to perform reflection on client types.
• Abstraction API – Common operations on the DOM (retrievingelements, setting styles and other manipulations) are automaticallytranslated by the library into browser-specific calls.
• Ajax – A set of client components is provided to handle Ajax requests and web-service calls.
• Application Services – The library allows accessing the ASP.NET Memership, Authentication, Roles and Profile services from the client side.

Recently, new features have been announced as part of the ASP.NET AJAX 4.0 release:

• Template Engine – Allows displaying data on the client side by using HTML templates and a custom binding notation. This approach avoids performing page rendering on the server side.
• Declarative instantiation of client components – Allows registration, instantiation and configuration of client components using markup code, without writing any imperative JavaScript code.
• Live Bindings – Synchronize element properties.

Hi Vipendra,

The Ajax can be achieved through the javascript, but it needs coding every time to implement that.

But the microsoft released these process through the ajax library, where it needs configuration and small amount coding to implement the Ajax in asp.net web page.
