如何让DevExpress TreeList的每个结点高亮显示？

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);



                Rectangle r = 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;

            }

       }
