Development and deployment of WebPart Based on ASP. NET AJAX
New article: AJAX joins hands with SOA on the new generation of Web2.0 application function StorePage () {d = document; t = d. selection? (D. selection. type! = ''None ''? D. selection. createRange (). text: ''') :( d. getSelection? D. getSelection (): '''); void (keyit = window. open (''http: // www.365key.com/storeit.aspx? T = ''+ escape (d. title) + ''& u ='' + escape (d. location. href) + ''& c ='' + escape (t), ''keyit'', ''scrollbars = no, width = 475, height = 575, left = 75, top = 20, status = no, resizable = yes ''); keyit. focus ();}

Windows SharePoint Services v3 is built based on ASP. NET 2.0. Microsoft ASP. net ajax 1.0 was launched after MOSS, so in some cases, ASP. there are some compatibility issues between net ajax and SharePoint, which will be solved in Windows SharePoint Services SP1. Before using ASP. net ajax technology in SharePoint, some special deployment steps are required.
Note:

The use of UpdatePanel in webpart is limited. For more information, see ASP. net ajax. Not all controls can be used in UpdatePanel.

If the output cache is enabled, ASP. net ajax cannot be used; otherwise, an error occurs. Classic performance conflicts with timeliness.

Benefits of using Microsoft ASP. net ajax 1.0 in SharePoint:
A complete set of client script resource library can be formed and some reusable parts can be accumulated.
JSON can be used to display our Web service data, and the results can be easily used in JavaScript/Ajax applications.
Using the extended technology to construct a WebPart can provide a highly interactive style, such as a textbox with the automatic completion function.
Use UpdatePanel in a WebPart to implement interaction without callback and reduce the number of page refreshes.
The following are the environment preparation steps before deploying components that use Microsoft ASP. net ajax 1.0 technology. (You only need to deploy it once in the newly installed environment and add Webpart in the future)

Download and install ASP. net ajax on the Web server farm

First, you must install "ASP. NET 2.0 AJAX Extensions 1.0", which can be downloaded from ajax.asp.net.
