DataGridView之编码列重绘

实现方式如下:

private void dgvRelation_RowPostPaint(object sender, DataGridViewRowPostPaintEventArgs e)
        {
            try
            {
                SolidBrush b = new SolidBrush(this.dgvRelation.RowHeadersDefaultCellStyle.ForeColor);
                e.Graphics.DrawString((e.RowIndex + 1).ToString(System.Globalization.CultureInfo.CurrentUICulture),
                    this.dgvRelation.DefaultCellStyle.Font, b, e.RowBounds.Location.X + 20, e.RowBounds.Location.Y + 4);
            }
            catch { return; }
        }

效果如下:

注意:使用该方式处理编号列的显示,需要处理cell_click事件,如: if (e.RowIndex == -1||e.ColumnIndex==-1) return;
