winform中DataGridView控件绘制序号

winform中DataGridView控件绑定如下图所示的序号(第一列的序号)：

 

后台代码如下：

        private void dgvQueue_RowPostPaint(object sender, DataGridViewRowPostPaintEventArgs e)
        {
            //绘制序号
            using (SolidBrush b = new SolidBrush(System.Drawing.Color.DarkRed))
            {
                e.Graphics.DrawString((e.RowIndex + 1).ToString(System.Globalization.CultureInfo.CurrentUICulture),
                                        e.InheritedRowStyle.Font, b,
                                        e.RowBounds.Location.X + 10,
                                        e.RowBounds.Location.Y + 4);
            }

       }
