DevExpress WinForm GridView 焦點行顯示下劃線高亮

欲實現以下效果，請直接調用複製代碼中的方法，在構造函數或者界面加載的時候調用即可

        /// <summary>
        /// 焦點行下劃線
        /// </summary>
        /// <param name="grid"></param>
        void DrawRowLine(GridControl grid)
        {
            grid.Paint += (s, e) =>
            {

                GridView gridView = grid.FocusedView as GridView;
                GridViewInfo viewinfo = gridView1.GetViewInfo() as GridViewInfo;
                GridViewRects gridViewRects = viewinfo.ViewRects;
                var focusedRowInfo = gridViewRects.ViewInfo.RowsInfo.GetInfoByHandle(gridView.FocusedRowHandle);
                if (focusedRowInfo != null)
                {
                    var r = focusedRowInfo.DataBounds;
                    Point p1 = new Point(r.X, r.Y + r.Height);
                    Point p2 = new Point(r.X + r.Width, r.Y + r.Height);
                    var pen = new Pen(Color.Yellow);
                    pen.Width = 2;

                    e.Graphics.DrawLine(pen, p1, p2);
                }
            };
            (grid.FocusedView as GridView).FocusedRowChanged += (s, e) =>
            {
                grid.Refresh();
            };
        }
