private:
   void treeView1_MouseUp( Object^ /*sender*/, MouseEventArgs^ e )
   {
      // If the right mouse button was clicked and released,
      // display the shortcut menu assigned to the TreeView.
      if ( e->Button == ::MouseButtons::Right )
      {
         treeView1->ContextMenu->Show( treeView1, Point(e->X,e->Y) );
      }
   }

private void treeView1_MouseUp(object sender, MouseEventArgs e)
{
   // If the right mouse button was clicked and released,
   // display the shortcut menu assigned to the TreeView. 
   if(e.Button == MouseButtons.Right)
   {
      treeView1.ContextMenu.Show(treeView1, new Point(e.X, e.Y) );      
   }
}

Private Sub treeView1_MouseUp(sender As Object, _
  e As MouseEventArgs) Handles treeView1.MouseUp
   ' If the right mouse button was clicked and released,
   ' display the shortcut menu assigned to the TreeView. 
   If e.Button = MouseButtons.Right Then
      treeView1.ContextMenu.Show(treeView1, New Point(e.X, e.Y))
   End If
End Sub
