Answer 1

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.Orange, new PointF(rect.Y, rect.X));

               e.Graphics.RotateTransform(90.0F);
               e.Graphics.TranslateTransform(0, -titleSize.Width);
               e.Handled = true;
           }
  }

In addition, you could set the AutoSizeColumnsMode property of the
DataGridView to AllCellsExceptHeader in order to make the DataGridView
compact.
