Exemplos

O seguinte exemplo de código mostra os Text valores das propriedades e Index de os TreeNode representados pela Parent propriedade de .TreeView.SelectedNode Este exemplo exige que tenhas um Form com um TreeView controlo sobre ele. Devem TreeView ter pelo menos dois nós raiz, cada um com pelo menos um nó filho.

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.";
      }
   }

private void treeView1_AfterSelect(object sender, TreeViewEventArgs e)
{  
   /* Display the Text and Index of the 
    * selected tree node's Parent. */
   if(e.Node.Parent!= null && 
     e.Node.Parent.GetType() == typeof(TreeNode) )
   {
      statusBar1.Text = "Parent: " + e.Node.Parent.Text + "\n"
         + "Index Position: " + e.Node.Parent.Index.ToString();
   }
   else
   {
      statusBar1.Text = "No parent node.";
   }
}

Private Sub treeView1_AfterSelect(sender As Object, _
  e As TreeViewEventArgs) Handles treeView1.AfterSelect
   ' Display the Text and Index of the 
   ' selected tree node's Parent. 
   If (e.Node.Parent IsNot Nothing) 
      If (e.Node.Parent.GetType() Is GetType(TreeNode)) Then
         statusBar1.Text = "Parent: " + e.Node.Parent.Text + _
           ControlChars.Cr + "Index Position: " + e.Node.Parent.Index.ToString()
      End If
   Else
      statusBar1.Text = "No parent node."
   End If
End Sub

Observações

Se o nó da árvore estiver ao nível raiz, a Parent propriedade devolve null.
