If you know the exact number of levels you can use a SiteMapPath like:
<asp:SiteMapPath runat="server" ParentLevelsDisplayed="1" />
Otherwise the SiteMapPath always goes direcly agains the SiteMapProvider currently in use and you can probably hook into the rendering of the SiteMapPath a do a check, like:
protected void SiteMapPath_ItemCreated(object sender, SiteMapNodeItemEventArgs e)
{
if (e.Item.ItemType == SiteMapNodeItemType.Root ||
(e.Item.ItemType == SiteMapNodeItemType.PathSeparator &&
e.Item.ItemIndex == 1))
{
e.Item.Visible = false;
}
}
that will make you SiteMapPath not showing the rootnode (and the first separator).
and if would like your node to display "Home" you can bind against another value, something like:
<asp:SiteMapPath ID="siteMapPath" runat="server"
Pathseparator="/"
OnItemCreated="SiteMapPath_ItemCreated">
<NodeTemplate>
<a href='<%# Eval("url") %>'><%# Eval("description") %></a>
</NodeTemplate>
<CurrentNodeTemplate>
<%# Eval("title") %>
</CurrentNodeTemplate>
</asp:SiteMapPath>
if description has a value of "Home" that will be shown.
