SiteMapProvider.GetChildNodes Method

Note: This method is new in the .NET Framework version 2.0.

When overridden in a derived class, retrieves the child nodes of a specific SiteMapNode.

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

public:
virtual SiteMapNodeCollection^ GetChildNodes (
	SiteMapNode^ node
) abstract
public abstract SiteMapNodeCollection GetChildNodes (
	SiteMapNode node
)
public abstract function GetChildNodes (
	node : SiteMapNode
) : SiteMapNodeCollection

Parameters

node

The SiteMapNode for which to retrieve all child nodes.

Return Value

A read-only SiteMapNodeCollection that contains the immediate child nodes of the specified SiteMapNode; otherwise, a null reference (Nothing in Visual Basic) or an empty collection, if no child nodes exist.

Classes that derive from the SiteMapProvider class must implement the abstract GetChildNodes method.

Notes to Inheritors When overriding the GetChildNodes method in a derived class, be sure to perform security trimming on the child nodes and ensure that the returned collection is read-only. The collection contains only the immediate children of the specified node.

The following code example demonstrates how to implement the GetChildNodes method in a class that implements the abstract SiteMapProvider class. The SimpleTextSiteMapProvider stores the hierarchical parent/child relationships in one Hashtable object and all SiteMapNode objects in another. The GetChildNodes method performs a reverse-lookup using both ArrayList objects.

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

No code example is currently available or this language may not be supported.
