gridcontrol 添加行号

    private void gridView1_CustomDrawRowIndicator(object sender, DevExpress.XtraGrid.Views.Grid.RowIndicatorCustomDrawEventArgs e)
        {
            if (e.Info.IsRowIndicator && e.RowHandle >= )
            {
                e.Info.DisplayText = (e.RowHandle + ).ToString();
            }
        }

有时候行号宽度不够 还需要设置： gridView1.IndicatorWidth = 75;
