备注
TreeView 控件用于以树形结构显示分层数据（如目录或文件目录），并支持下列功能：
支持数据绑定，从而允许将该控件的节点绑定到 XML、表格或关系数据。
通过与 SiteMapDataSource 控件集成提供对站点导航的支持。
可以显示为纯文本或超链接的节点文本。
通过编程访问 TreeView 对象模型，动态地创建树、填充节点以及设置属性等。
客户端节点填充（在支持的浏览器上）。
能够在每个节点旁边显示复选框。
能够通过主题、用户定义的图像和样式自定义外观。
有关 TreeView 控件的更多信息，请参见 TreeView Web 服务器控件概述。
示例
下面的代码示例演示如何将 TreeView 控件绑定到 XML 数据源。
