SiteMapProvider.GetParentNode Method

When overridden in a derived class, retrieves the parent node of a specific SiteMapNode object.

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

public:
virtual SiteMapNode^ GetParentNode (
	SiteMapNode^ node
) abstract
public abstract SiteMapNode GetParentNode (
	SiteMapNode node
)
public abstract function GetParentNode (
	node : SiteMapNode
) : SiteMapNode
Not applicable.

Parameters

node

The SiteMapNode for which to retrieve the parent node.

Return Value

A SiteMapNode that represents the parent of node; otherwise, a null reference (Nothing in Visual Basic), if the SiteMapNode has no parent or security trimming is enabled and the parent node is not accessible to the current user.
NoteNote:

GetParentNode might also return a null reference (Nothing in Visual Basic) if the parent node belongs to a different provider. In this case, use the ParentNode property of node instead.

The following code example demonstrates how to implement the GetParentNode method in a class that implements the abstract SiteMapProvider class. The SimpleTextSiteMapProvider stores the hierarchical parent/child relationship between SiteMapNode objects in an IList interface, such as an ArrayList object.

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