Tutorial: Introduction to AJAX in ASP.NET 2.0 and VB

[commando]

AJAX, short for Asynchronous JavaScript And XML, isn't a technology but rather a grouping of technologies. AJAX uses a communication technology (typically SOAP and XML) to send and receive an asynchronous request/response to the server, and then leverages presentation technologies (JavaScript, DOM, HTML, and CSS) to process the response. Applications using AJAX are legitimate today, because most browsers support the necessary technology.

First thing we need to do is to import the AJAX namespace from Ajax.DLL.The Ajax namespace contains Ajax.dll encapsule Asynchronous Javascript and XML in Bin folder. This is an combination of Javascript and XML. The data is transfered in the form of XML.

Imports Ajax
Imports System.Data.SqlClient
Imports System.Data


In this tutorial, the only configuration step beyond that is to add the following code in the web.config file, inside the <system.web> element.


<httpHandlers>
<add verb="POST,GET" path="ajax/*.ashx" type="Ajax.PageHandlerFactory, Ajax"/>
</httpHandlers>
