Hi,
Write a basic site map inline coding as the following format in Master Page
<asp:SiteMapPath CssClass="text_left_normal" ID="SiteMapPath1" runat="server" RenderCurrentNodeAsLink="false">
</asp:SiteMapPath>
<asp:SiteMapDataSource ID="SiteMapDataSource1" runat="server" />
and write a xml file as following
<?xml version="1.0" encoding="utf-8" ?>
<siteMap>
<siteMapNode title="Home" url="~/test/testHomePage.aspx" >
<siteMapNode title ="RootNOde" url ="test/rootNode.aspx">
<siteMapNode title ="test1" url ="test/test1.aspx" ></siteMapNode>
<siteMapNode title ="test2" url ="test/test2.aspx" ></siteMapNode>
<siteMapNode title ="test3" url ="test/test3.aspx" ></siteMapNode>
<siteMapNode title ="test4" url ="test/test4.aspx" ></siteMapNode>
</siteMapNode>
<siteMapNode title ="RootNOde2" url ="test/rootNode.aspx">
<siteMapNode title ="test_test1" url ="test/"test_test1" .aspx" ></siteMapNode>
<siteMapNode title ="test_test2" url ="test/"test_test2" .aspx" ></siteMapNode>
<siteMapNode title ="test_test3" url ="test/"test_test3" " ></siteMapNode>
<siteMapNode title ="test_test4" url ="test/"test_test4" .aspx" ></siteMapNode>
</siteMapNode>
</siteMapNode>
</siteMap>
-then you can set datasoruce as the XML File,
