Examples

The SPNavigationProvider class allows you to write custom controls to navigate a site. The following sample code accesses the root node for the Top Link Bar and Quick Launch. From that point, a user can navigate both node hierarchies.

<% @Page language="C#" Debug=true%>
<%@ Register Tagprefix="SharePoint" 
      Namespace="Microsoft.SharePoint" 
      Assembly="Microsoft.Sharepoint" %>
<%@ Register Tagprefix="SharePointNavigation"
      Namespace="Microsoft.SharePoint.Navigation"
      Assembly="Microsoft.Sharepoint" %>
<%@ Register Tagprefix="SharePointWebControls"
      Namespace="Microsoft.SharePoint.WebControls"
      Assembly="Microsoft.Sharepoint" %>
<HTML>
      <BODY>
            Tests the SPNavigationProvider properties
            <BR>
            <%

SPWeb web = SPControl.GetContextWeb(Context);

SPNavigationProvider prov = (SPNavigationProvider)
      SiteMap.Providers["SPNavigationProvider"];

Response.Write ("<BR><DIV ID =\"quicklaunch\">" +
       prov.FindSiteMapNode(Context).Title + "</DIV>");
Response.Write("<BR><DIV ID=\"toplink\">" +
      prov.FindSiteMapNode("sid:1002") + "</DIV>");

%>
