我想通过相对源将我的 DataTemplate (ClosableTabItemTemplate) 绑定到 HeaderedContentControl 的 Workspaces DataContext。不幸的是它不起作用?有任何想法吗?
顺便说一句:我收到以下命令行错误:System.Windows.Data 错误:40:BindingExpression 路径错误:在“对象”“AllUserView”(名称=“”)上找不到“DisplayName”属性。BindingExpression:Path=DataContext.DisplayName; DataItem='TabItem' (名称=''); 目标元素是'ContentPresenter'(名称='');目标属性是“内容”(类型“对象”)
