当使用Treeview控件绑定Sitemap文件时，首先引入SiteMapDataSource，但是不用显示指点它的datasource file，它会自动绑定到Web.sitemap，但是注意这时的Web.sitemap要放在根目录下，否则会出现类似XmlDataSource找不到Web.sitemap的错误。
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>Untitled Page</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:SiteMapDataSource ID="SiteMapDataSource1" runat="server" />
<asp:TreeView ID="TreeView1" runat="server" DataSourceID="SiteMapDataSource1">
</asp:TreeView>
</div>
</form>
</body>
</html>
////Web.sitemap
<?xml version="1.0" endoding="utf-8" ?>
<siteMap xmlns=http://schemas.microsoft.com/AspNet/SiteMap-File-1.0 >
<siteMapNode url="" title="home" description="">
<siteMapNode url="" title="parent" description="" />
<siteMapNode url="" title="child" description="" />
</siteMapNode>
</siteMap>
运行结果为
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>Untitled Page</title>
</head>
<body>
<form id="form1" runat="server">

<asp:TreeView ID="TreeView1" runat="server" DataSourceID="SiteMapDataSource1">
