如何让DXperience TreeList的每个节点高亮显示？

效果如下：

代码如下：

private void treeList1_CustomDrawNodeCell(object sender, DevExpress.XtraTreeList.CustomDrawNodeCellEventArgs e)

       {

            TreeList node = sender as TreeList;

            if(e.Node == node.FocusedNode)

            {

                e.Graphics.FillRectangle(SystemBrushes.Window, e.Bounds);

                Rectangler = new Rectangle(e.EditViewInfo.ContentRect.Left,
                                           e.EditViewInfo.ContentRect.Top,
                                            Convert.ToInt32(e.Graphics.MeasureString(e.CellText,treeList1.Font).Width + 1),
                                            Convert.ToInt32(e.Graphics.MeasureString(e.CellText,treeList1.Font).Height));

                e.Graphics.FillRectangle(SystemBrushes.Highlight, r);

               e.Graphics.DrawString(e.CellText, treeList1.Font, SystemBrushes.HighlightText, r);

                e.Handled = true;
            }
       }
