推荐答案

最简单的方法是使用在父表单和子表单之间共享的单个ViewModel.只要您以两种形式绑定到相同的ObservableCollection，就会看到相同的数据.

The easiest way to accomplish this is to use a single ViewModel that is shared between both the parent and the child form. As long as you bind to the same ObservableCollection in both forms, you will see the same data.
