C# 如何使radtreeview中的选定项应用样式（或）在使用radpane时高亮显示radtreeview选定项？

代码：

---

使用Radpane后，所选项目未应用样式如果单独使用RadTreeView（没有radpane），RadTreeView中的选定项目具有正常工作的样式

SelectionUnfocusedVisual

（即，选定项目高亮显示）。如何使radtreeview中的选定项应用样式（或）在使用radpane时高亮显示radtreeview选定项？。谢谢

我找到了解决办法。也就是说，一旦我们选择了

radtreeviewitem

解决方案：

this.radDocking.UpdateLayout（）
