Gets the specified sibling of the
UltraTreeNode.
Parameters
- nodePosition
- Specifies which sibling to get relative to the node.
Return Value
A reference to the
UltraTreeNode or
Nothing if there is no matching sibling.
The following sample code illustrates how to calculate the number of nodes in a tree.

Dim totalNodesInTree As Integer
Dim nonRootNodes As Integer
Dim node As UltraTreeNode
' Call the tree control's 'GetNodeCount' method
' with true to get the total numder of nodes
' in the tree.
totalNodesInTree = Me.ultraTree1.GetNodeCount(True)
Debug.WriteLine("Total nodes in tree = " + totalNodesInTree.ToString())
Debug.Indent()
' Get the first root node
node = Me.ultraTree1.Nodes(0)
While Not node Is Nothing
' Add in root node's descendant nodes.
nonRootNodes += node.GetNodeCount(True)
' Get the next root node
node = node.GetSibling(NodePosition.Next)
End While
Debug.WriteLine("root nodes = " + Me.ultraTree1.Nodes.Count.ToString())
Debug.WriteLine("non-root nodes = " + nonRootNodes.ToString())
Debug.IndentLevel = 0
End Sub
