SiteMapProvider.GetParentNodeRelativeToCurrentNodeAndHintDownFromParent Method
Assembly: System.Web (in system.web.dll)
public: virtual SiteMapNode^ GetParentNodeRelativeToCurrentNodeAndHintDownFromParent ( int walkupLevels, int relativeDepthFromWalkup )
public SiteMapNode GetParentNodeRelativeToCurrentNodeAndHintDownFromParent ( int walkupLevels, int relativeDepthFromWalkup )
public function GetParentNodeRelativeToCurrentNodeAndHintDownFromParent ( walkupLevels : int, relativeDepthFromWalkup : int ) : SiteMapNode
Parameters
- walkupLevels
The number of ancestor node levels to traverse when retrieving the requested ancestor node.
- relativeDepthFromWalkup
The number of descendant node levels to retrieve from the target ancestor node.
Return Value
A SiteMapNode that represents an ancestor SiteMapNode of the currently requested page; otherwise, a null reference (Nothing in Visual Basic), if the current or ancestor SiteMapNode is not found or cannot be returned for the current user.The default implementation of the SiteMapProvider class provides a non-optimized implementation of the GetParentNodeRelativeToCurrentNodeAndHintDownFromParent method, calling the GetCurrentNodeAndHintAncestorNodes and HintNeighborhoodNodes methods; however, site map providers can override the GetParentNodeRelativeToCurrentNodeAndHintDownFromParent method and provide an optimized implementation that uses custom caching mechanisms to return the ancestor node and perform an optimized lookup of the other SiteMapNode objects.
The walkupLevels parameter is used to specify how many levels of parent and ancestor nodes to traverse when retrieving the target node. If fewer levels exist than are requested, a null reference (Nothing in Visual Basic) is returned. The downLevel parameter is used to specify how many levels of descendant nodes from the target ancestor node to retrieve. If preferred, the ancestor and descendant nodes can be linked to the SiteMapNode that is returned by the GetParentNodeRelativeToCurrentNodeAndHintDownFromParent method, using the ParentNode and ChildNodes properties.
