Property Value

Type: System::Int32

A zero-based index value that represents the position of the tree node in the Nodes collection.

The following code example displays the Text and Index property values of the TreeNode represented by the Parent property of the TreeView::SelectedNode. This example requires that you have a Form with a TreeView control on it. The TreeView should have at least two root nodes, each having at least one child node.

private:
   void treeView1_AfterSelect( Object^ /*sender*/, TreeViewEventArgs^ e )
   {
      /* Display the Text and Index of the
            * selected tree node's Parent. */
      if ( e->Node->Parent != nullptr && e->Node->Parent->GetType() == TreeNode::typeid )
      {
         statusBar1->Text = String::Format( "Parent: {0}\n Index Position: {1}", e->Node->Parent->Text, e->Node->Parent->Index );
      }
      else
      {
         statusBar1->Text = "No parent node.";
      }
   }
