最后，您还可以使用事件发布系统（例如MVVM Light Messenger）在点击按钮时发布事件，该按钮是调查的响应按钮。我在从Eric那里得到答案方面得到了很大帮助，Eric是给出另一个答案的人。
为了在嵌入到自己复杂设计中的两个类之间进行通信，一种方法是使用EventAggregator模式。碰巧，我正在开发的应用程序使用Prism作为自己的EventAggregator实现。此模式使您能够发布由接收类上的subscribe事件拾取的有效负载。我确信您的答案是正确的，但我无法将其连接起来。当我点击按钮时，什么也没发生。顺便说一句，我对ViewModel树的看法是错误的。SurveyPageViewModel包含1个SurveyViewModel，其中包含1个SelectedSection，其中包含一组QuestionViewModel对象。命令事件位于SurveyPageViewModel类上。因此，对我来说有意义的是，在识别ListView的名称时，然后在按钮“Path=DataContext.DESIRED_COMMAND”中。该按钮位于UserControl文件中，与LIstView不在同一文件中。这就是问题所在吗？顺便说一下，将SurveyPageViewModel的引用传递给QuestionViewModel将创建一个循环引用，因此我认为这不起作用。我不熟悉MVVM Light Messenger。我查过了，但它看起来很复杂（我是XAML新手），我已经更新了答案，这样你就可以看到我做了什么。你可以发布完整的XAML文件，这样我就可以看到哪些项在彼此的作用域中了吗？好的。我原以为ListView和按钮在同一个范围内（或者至少在文件中）。XAML ElementName绑定无法工作。我的最佳建议是使用类似MVVM Light Messenger类（）的发布订阅。
public ICommand SaveThenPreviousSectionCommand { get; private set; }
public ICommand SaveThenNextSectionCommand { get; private set; }
SaveThenPreviousSectionCommand = new DelegateCommand(DoSaveThenPreviousSection);
SaveThenNextSectionCommand = new DelegateCommand(DoSaveThenNextSection);
private async void DoSaveThenPreviousSection()
{
var i = 1;
}
private async void DoSaveThenNextSection()
