MOSS AJAX WebParts开发环境设置

 

置顶：MOSS SP1开始支持AJAX。首先确认你的MOSS版本号

想必开发过MOSS AJAX控件的都知道，为了实现AJAX，必须对MOSS的环境进行大量的设置。网上有大量此类的文章，其中最流行的做法应该是刊登在moss开发团队blog上的（点击下面的URL进入）。

（http://blogs.msdn.com/sharepoint/archive/2007/03/02/integrating-asp-net-ajax-with-sharepoint.aspx）

简单概括一下步骤的话：
1.    下载并安装ASP.NET AJAX（ http://www.asp.net/ajax/）
2.    扩展web.config使其支持ASP.NET AJAX
3.    在master pager上添加ASP.NET AJAX Script Manager
 
算得上是官方推荐的做法吧，只是有点麻烦，好在对MOSS进行AJAX扩展的人越来越多，网上出现了很多简便的做法，下面是鄙人的心得
1.    下载并安装ASP.NET AJAX
2.    下载并安装stsadm.ajaxifymoss自动配置web.config
3.    Webparts的OnInit事件里添加ASP.NET AJAX Script Manager
 

接下来对各个步骤进行介绍

1       下载并安装ASP.NET AJAX（ http://www.asp.net/ajax/）
推荐安装ASP.NET AJAX Extensions 1.0版本。

2       下载并安装stsadm.ajaxifymoss自动配置web.config
（http://www.codeplex.com/ajaxifymoss/Release/ProjectReleases.aspx?ReleaseId=13360）
2.1      下载StsAdm.AjaxifyMoss.zip并解压，执行deploy.cmd后执行upgrade.cmd（StsAdm.AjaxifyMoss.zip必须在同一个文件夹内）
2.2      启动dos命令栏窗口（cmd），使用stsadm运行ajaxifying（默认在C:/Program Files/Common Files/Microsoft Shared/web server extensions/12/BIN）
全部命令如下

功能	使用例
add asp.net ajax to web.config	stsadm -o addajax -url http://your.moss.webapplication
remove asp.net ajax from web.config	stsadm -o removeajax -url http://your.moss.webapplication
add .Net 3.5 ajax to web.config	stsadm -o addajax35 -url http://your.moss.webapplication
remove .Net 3.5 ajax from web.config	stsadm -o removeajax35 -url http://your.moss.webapplication

      
3       Webparts的OnInit事件里添加ASP.NET AJAX Script Manager（参考示例代码）
4       运行示例代码(不要忘记添加System.Web.Extensions)
(如果运行成功并且不发生全页面刷新现象，那么就说明配置成功。WebParts开发使用Visual Studio 2005 Extensions, Version 1.1，2008请使用V1.2)
