我在 usercontrol 内的网格内的 stackpanel 内的 itemscontrol 内的 controltemplate 内有一个 stackpanel（参见下面的 xaml）。在内部堆栈面板中有一个标签 (Name="NoComponentChosen") 和另一个堆栈面板 (Name="ComponentChosen")。标签的可见性最初是折叠的。
控制模板有一个带有绑定的数据触发器。当绑定引用具有特定值时，标签 (NoComponentChosen) 变为可见并且堆栈面板折叠。
当我在用户界面中切换时，我想跳过标签/堆栈面板。我还希望仍然能够通过我的 ChangeRequestView.xaml 中的其余内容（列表框和按钮）进行选项卡。
现在——当我选择标签时——标签/堆栈面板最终被选中并被一个虚线矩形包围。这就是我想避免的。
这是我的 ChangeRequestView.xaml：

整个 UserControl/ChangeRequestView.xaml 是我的 MainWindow 的一部分——我不知道这是否有什么要说的。我在我的 MainWindow 中浏览所有不同的视图，当我到达 ChangeRequestView 时，我想根据其中哪些没有折叠来跳过标签/堆栈面板。
这是我的 MainWindow.xaml：

对于长 xaml 文件，我深表歉意，但我认为我提供给您的信息越多，您就越容易帮助我解决这个选项卡问题。
当我通过用户界面进行选项卡时，您对如何跳过标签“NoComponentChosen”/堆栈面板“ComponentChosen”有任何想法吗？
