SiteMap.CurrentNode Property
Assembly: System.Web (in system.web.dll)
/** @property */ public static SiteMapNode get_CurrentNode ()
public static function get CurrentNode () : SiteMapNode
Not applicable.
Property Value
A SiteMapNode instance that represents the currently requested page; otherwise, a null reference (Nothing in Visual Basic), if no representative node exists in the site map information.The SiteMap class retrieves the CurrentNode property by requesting it from the provider.
If no representative node exists for the page in the site map information, or if security trimming is enabled and the node cannot be returned for the current user, a null reference (Nothing in Visual Basic) is returned.
The SiteMapResolve event is raised by the default site map provider if one or more subscriptions exist.
If you implement your own SiteMapProvider object, you might create your own mechanism to find and retrieve the CurrentNode. However, if you extend the StaticSiteMapProvider class and use a URL-based scheme to identify pages, you can override the FindSiteMapNode method.
The following code example demonstrates how to use the CurrentNode property to retrieve the SiteMapNode object that represents the current page.
<script runat="server"> private void Page_Load(object sender, System.EventArgs e) { // Examine the CurrentNode, and navigate the SiteMap relative to it. Response.Write(SiteMap.CurrentNode.Title + "<br />"); Response.Write("<font COLOR='red'>" + SiteMap.CurrentNode.Url + "</font><br />"); // What nodes are children of the CurrentNode? if (SiteMap.CurrentNode.HasChildNodes) { IEnumerator childNodesEnumerator = SiteMap.CurrentNode.ChildNodes.GetEnumerator(); while (childNodesEnumerator.MoveNext()) { // Prints the Title of each node. Response.Write(childNodesEnumerator.Current.ToString() + "<br />"); } } Response.Write("<hr />"); // Examine the RootNode, and navigate the SiteMap relative to it. Response.Write(SiteMap.RootNode.Title + "<br />"); Response.Write(SiteMap.RootNode.Url + "<br />"); // What nodes are children of the RootNode? if (SiteMap.RootNode.HasChildNodes) { IEnumerator rootNodesChildrenEnumerator = SiteMap.RootNode.ChildNodes.GetEnumerator(); while (rootNodesChildrenEnumerator.MoveNext()) { // Prints the Title of each node. Response.Write(rootNodesChildrenEnumerator.Current.ToString() + "<br />"); } } } </script>
