使用Datalist和SiteMapDataSource构建页面导航条

        <asp:DataList ID="DataList1" runat="server" Style="z-index: 101; left: 25px; position: absolute;
            top: 69px" DataSourceID="SiteMapDataSource1" RepeatDirection="Horizontal">
            <ItemTemplate>
                <a href='<%#Eval("url")%>'><%#Eval("title")%></a>
            </ItemTemplate>
        </asp:DataList>
        <asp:SiteMapDataSource ID="SiteMapDataSource1" runat="server" ShowStartingNode="False" />
