GridControl如何顯示行號

        //要設置一下.IndicatorWidth，要不然列會被遮擋

       this.gridView1.IndicatorWidth = 40;

       //顯示行的序號

        private void gridView1_CustomDrawRowIndicator(object sender, RowIndicatorCustomDrawEventArgs e)

        {

            if (e.Info.IsRowIndicator && e.RowHandle>=0)

            {

                e.Info.DisplayText = (e.RowHandle + 1).ToString();

            }

         }
