</DockPanel>

使用Radpane后，所选项目未应用样式。 如果单独使用RadTreeView（没有radpane），则radtreeview中的所选项目具有正常工作的样式SelectionUnfocusedVisual（即），所选项目突出显示。如何在radtreeview中使所选项目应用（或）样式以在使用radpane时突出显示radtreeview所选项目？谢谢。

我找到了解决方案。我们需要在选择RadDocking

后更新radtreeviewitem布局

解决方案：

this.radDocking.UpdateLayout();

在使用radpane时，如何使radtreeview中的选定项目应用（或）样式以突出显示radtreeview所选项目？
