这个xaml都没有出现在设计师中，我对wpf一般都不太熟悉，但我确信至少其中一些可以在设计师中出现。

这是传统/棕色代码。我觉得我对Wpf Windows非常可靠，但还没有想出DataTemplate或Style s
所以我似乎错过了这个家伙如何解决或重新清理它的重要部分，初始化后的代码：
private void DifferentialDiagnosisTab_Loaded(object sender, RoutedEventArgs e)
{
vm = new DifferentialDiagnosisTabViewModel();
this.Content = vm;
}
答案 0 :(得分：2)
它没有出现在设计师中，因为as Johan Larsson noted，没有什么可以展示的。您已完成的任务是定义一组控件可能使用的资源 - Style和DataTemplate资源，即。
获取整个<Grid>代码（移除其现在为空的父代<DataTemplate>）并将其移出<UserControl.Resources>代码（在</UserControl>结束代码之前）。不确定这会给你什么你想要的（我只是只看了一下标记），但是你已经拥有了那个＆＃34;啊-HA＆＃34;时刻; - ）
在典型的 Model-View-ViewModel 设置中，ViewModel不是内容（您的代码正在设置控件{{1}在运行时，这就是设计时没有出现的原因），它是Content，而XAML使用绑定到ViewModel的属性。
你不应该有这样的代码隐藏。
