C# datagridview printing with vertical columns

Hi..
    This code will help you to display Vertically Column as like above diagram.
   Please try below code....

 
  private void frmDataGridTesting_Load(object sender, EventArgs e)
  {
     dtSam = new DataTable();
      string sSQLTemp = "Your Select Query";
     dtSam = oDBTools.SetSelectQuery(sSQLTemp);
     ArrayList columnHeading=new ArrayList () ;
     foreach (DataColumn dc in dtSam.Columns)   
    {
   columnHeading.Add(dc.ColumnName);
    }
    if (columnHeading.Count > 0)
   {
   dataGridView1.ColumnHeadersHeightSizeMode = DataGridViewColumnHeadersHeightSizeMode.EnableResizing;
   dataGridView1.ColumnHeadersHeight = 50;
   //dataGridView1.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.AllCellsExceptHeader;
   }
  dataGridView1.DataSource = dtSam;
}

  private void dataGridView1_CellPainting(object sender, DataGridViewCellPaintingEventArgs e)
 {
   if (e.RowIndex == -1 && e.ColumnIndex >= 0)
    {
     e.PaintBackground(e.ClipBounds, true);
    Rectangle rect = this.dataGridView1.GetColumnDisplayRectangle(e.ColumnIndex, true);
    Size titleSize = TextRenderer.MeasureText(e.Value.ToString(), e.CellStyle.Font);
   if (this.dataGridView1.ColumnHeadersHeight < titleSize.Width)
    {
       this.dataGridView1.ColumnHeadersHeight = titleSize.Width;
    }
    e.Graphics.TranslateTransform(0, titleSize.Width);
   e.Graphics.RotateTransform(-90.0F);
     e.Graphics.DrawString(e.Value.ToString(), this.Font, Brushes.Black, new PointF(rect.Y -      (dataGridView1.ColumnHeadersHeight - titleSize.Width), rect.X));
     e.Graphics.RotateTransform(90.0F);
     e.Graphics.TranslateTransform(0, -titleSize.Width);
     e.Handled = true;
    }
 }

   If you got correct solution then mark as Accepted Answer.
