SiteMapProvider::GetParentNode Method
When overridden in a derived class, retrieves the parent node of a specific SiteMapNode object.
Assembly: System.Web (in System.Web.dll)
Parameters
- node
- Type: System.Web::SiteMapNode
The SiteMapNode for which to retrieve the parent node.

GetParentNode might also return nullptr 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.
