Configure the Ajax Environment

A Brief Introduction to Ajax. In the 2.0 era, Microsoft successfully launched ASP. NET Ajax technology after ASP. NET to Implement Asynchronous networks. Ajax is called asynchronous between crip and XML. As the name suggests, this technology can implement Part of the browser content and avoid submitting the browser content to the server.

Compared with traditional web technologies, ASP. NET Ajax has the following three main differences --

1. Update part of the page to communicate with the server without any refresh;

2. asynchronous page operations are performed on the same server to make the page more responsive;

3. The page interacts with the server to improve application efficiency.

To be able to use Ajax technology, we need to build a development environment. What makes me happy is that ASP. NET Ajax is free of charge, can download directly from Microsoft official website http://ajax.asp.net! Open the page, find ASP. NET extensions V1.0 and download it. Make sure that the machine meets the following prerequisites before installation --

1. The operating system is windows, such as server 2003, XP Home, XP Professional, and Vista)

2. Install. NET Framework 2.0 or a later version (generally 3.0)

3. IE 5.01 or later. (It is estimated that everyone is not 6.0 or 7.0)

The installer is only 1.36mb in size, and the download speed is very fast. Click Install, and then the classic "Next". finsh is the finsh! After the installation is successful, open VS 2005 and you will find an additional tab [Ajax extensions] in the [toolbox], which contains the Web server control --

In addition to pointers, the remaining five main controls will be learned one by one in the future.

Now you can use ASP. NET Ajax! Ajaxstart, an example similar to "Hello World", is used to create a form page of [ASP. NET Ajax-Enable Web site] to view the HTML code and web. config configuration file.
