DataGridView加上默认的序号

DataGridView自动添加序号

DataGridView找到RowPostPaint事件

  private void dg_item_info_RowPostPaint(object sender, DataGridViewRowPostPaintEventArgs e)
        {
            SetDataGridViewIndex(this.dg_item_info, e);    
        }
        
　　　　　// 设置分页属性
        private static int pageIndex1 = 1;
        private static int pageSize1 = 10;
         /// <summary>
        /// 给GridView 添加默认序号
        /// </summary>
        public static void SetDataGridViewIndex(DataGridView dgv, DataGridViewRowPostPaintEventArgs e)
        {
            Rectangle rectangle = new Rectangle(e.RowBounds.Location.X,
                                                e.RowBounds.Location.Y,
                                                 dgv.RowHeadersWidth - 4,
                                                e.RowBounds.Height);
            TextRenderer.DrawText(e.Graphics,
                                  (e.RowIndex + 1 + ((pageIndex1 - 1) * pageSize1)).ToString(),
                                    dgv.RowHeadersDefaultCellStyle.Font,
                                   rectangle,
                                    dgv.RowHeadersDefaultCellStyle.ForeColor,
                                   TextFormatFlags.VerticalCenter | TextFormatFlags.Right);
        }
