Question

I have a sitemap like this :

<?xml version="1.0" encoding="utf-8" ?>
<siteMap>
  <siteMapNode title="Home" >
    <siteMapNode title="Services" >
      <siteMapNode title="Training" url="~/Training.aspx"/>
    </siteMapNode>
  </siteMapNode>
</siteMap>

now I wanna to show second level of sitemap in separate division.

<asp:SiteMapDataSource ID="SiteMapDataSource1" runat="server" ShowStartingNode="false" />
<asp:Repeater runat="server" ID="menu" DataSourceID="SiteMapDataSource1"> 
    <asp:HyperLink ID="menu_items" runat="server" NavigateUrl='<%# Eval("Url") %>'><%# Eval("Title") %></asp:HyperLink>
</asp:Repeater>
<div class="separator"></div>
//Here must child Node(s) displayed
//e.g. return <a href="~Training.aspx">Training</a>

To display the children for the Basic Reporting, Filtering Reports, and Customized Formatting SiteMapNodes, we can add another Repeater to the initial Repeater’s ItemTemplate. This second Repeater will be bound to the SiteMapNode instance’s ChildNodes property, like so:

<asp:Repeater runat="server" ID="menu" DataSourceID="SiteMapDataSource1">
    <ItemTemplate>
        <li>
            <asp:HyperLink runat="server" NavigateUrl='<%# Eval("Url") %>'><%# Eval("Title") %></asp:HyperLink>

            <asp:Repeater runat="server" DataSource='<%# ((SiteMapNode) Container.DataItem).ChildNodes %>'>
                <HeaderTemplate>
                    <ul>
                </HeaderTemplate>

                <ItemTemplate>
                    <li>
                        <asp:HyperLink runat="server" NavigateUrl='<%# Eval("Url") %>'><%# Eval("Title") %></asp:HyperLink>
                    </li>
                </ItemTemplate>

                <FooterTemplate>
                    </ul>
                </FooterTemplate>
            </asp:Repeater>
        </li>
    </ItemTemplate>
</asp:Repeater>

These two Repeaters result in the following markup (some markup has been removed for brevity):

<li>
    <a href="/Code/BasicReporting/Default.aspx">Basic Reporting</a>
    <ul>
       <li>
          <a href="/Code/BasicReporting/SimpleDisplay.aspx">Simple Display</a>
       </li>
       <li>
          <a href="/Code/BasicReporting/DeclarativeParams.aspx">Declarative Parameters</a>
       </li>
       <li>
          <a href="/Code/BasicReporting/ProgrammaticParams.aspx">Setting Parameter Values</a>
       </li>
    </ul>
</li>

<li>
    <a href="/Code/Filtering/Default.aspx">Filtering Reports</a>
    ...
</li>

<li>
    <a href="/Code/CustomFormatting/Default.aspx">Customized Formatting</a>
    ...
</li>
