        {
            int x_value;

            for (int i = 0; i < 5; ++i)
            {
                DataRow dr =
                         ((DataTable)wddgv.DataSource).Rows[i + row];
                x_value = 0;

                // draw a solid line
                g.DrawLine(Pens.Black, new Point(0, y_value),
                        new Point(this.Width, y_value));

                foreach (DataGridViewColumn dc in wddgv.Columns)

                                             (float)x_value, (float)y_value + 10f);

                    x_value += dc.Width + 5;
                }

                y_value += 40;
            }
