CurrentNode Property

SiteMapProvider.CurrentNode Property


Gets the SiteMapNode object that represents the currently requested page.

Namespace:   System.Web
Assembly:  System.Web (in System.Web.dll)

public virtual SiteMapNode CurrentNode { get; }

Property Value

Type: System.Web.SiteMapNode

A SiteMapNode that represents the currently requested page; otherwise, null, if the SiteMapNode is not found or cannot be returned for the current user.

The SiteMapResolve event is raised before attempting to retrieve a SiteMapNode object, to enable event subscribers to return an instance of the SiteMapNode class. If there are no event subscribers, the SiteMapProvider class calls the FindSiteMapNode method using the current HTTP context to retrieve a SiteMapNode that represents the currently requested page.

If the currently requested page does not correspond with a SiteMapNode, null is returned. If security trimming is enabled and the user is not permitted to access the SiteMapNode, null is returned.

The following code example demonstrates how to implement the CurrentNode property in a class that implements the abstract SiteMapProvider class.

This code example is part of a larger example provided for the SiteMapProvider class.

// Implement the CurrentNode property.
public override SiteMapNode CurrentNode
    string currentUrl = FindCurrentUrl();
    // Find the SiteMapNode that represents the current page.
    SiteMapNode currentNode = FindSiteMapNode(currentUrl);
    return currentNode;

// Implement the RootNode property.
public override SiteMapNode RootNode
    return rootNode;
