protected override void OnPaint(PaintEventArgs e)
  {
   String drawString = "Sample Text";
   Font drawFont = new Font("Arial", 16);
   SolidBrush drawBrush = new SolidBrush(Color.Black);
   float x = 150.0F;
   float y =  50.0F;
   StringFormat drawFormat = new StringFormat();
   drawFormat.FormatFlags = StringFormatFlags.DirectionVertical;
   e.Graphics.DrawString(drawString, drawFont, drawBrush, x, y, drawFormat);
   base.OnPaint (e);
  }
