【IT168技术文档】
Sharepoint中的数据视图(DataFormWebPart)有着非常重要的作用，特别是在需要定制自己的页面显示格式的时候。
数据视图可以将列表，比如通知列表、博客列表、链接列表等转换成数据视图，然后可以任意控制显示格式
数据视图可以从多个数据源取数据来显示，这里的数据源可以是子网站中的列表、可以是数据库中的记录、可以是其它网站的 RSS源
数据视图可以实现分页、排序、查询、过滤等功能
数据视图可以利用ddwrt:IfHasRights实现权限的判断.....
基本的功能我就不说了，下面列出我在开发中觉得比较有用的、不太注意到的一些功能。
首先给出一个最简单的数据视图的代码：
