Property Value

The parent node of the ContextNode.

Remarks

Returns a null reference (Nothing in Visual Basic) if this is the RootNode.

Example

This example uses a System.Windows.Controls.TreeView, theTreeView, where each TreeViewItem has its System.Windows.FrameworkElement.Tag property set to a ContextNode. It finds the selected node and then uses ParentNode to find its parent. After the parent node is found, it calls the MarkNodeAsRed method to change the node's strokes to red.

Dim selectedNode As ContextNode = CType(selectedTreeItem.Tag, ContextNode)
Dim parentNode As ContextNode = selectedNode.ParentNode
If Not (parentNode Is Nothing) Then
    MarkNodeAsRed(parentNode)
End If

ContextNode selectedNode = (ContextNode)selectedTreeItem.Tag;
ContextNode parentNode = selectedNode.ParentNode;
if (parentNode != null)
{
    MarkNodeAsRed(parentNode);
}
