MVVM，使用新的Windows还是View？ [英] MVVM, use new Windows or Views?
问题描述
在完成一些常规项目之后，我最近的项目使用Caliburn.Micro实现了MVVM模式-但我仍然遇到一些体系结构问题。主要是：
After finishing some by-hand projects, my recent project implements the MVVM pattern using Caliburn.Micro - but I still struggle with some architectural problems. Mainly:
我的ViewModel包含一个 BindableCollection ProfilesCollection 个人资料。我的视图有一个添加新配置文件的按钮。但是由于配置文件很复杂，我希望单击按钮以打开一个新窗口，在其中可以填写详细信息，然后返回到主窗口。
My ViewModel contains a BindableCollection ProfilesCollection of Profiles. My view has a button to add new profiles. But since the profiles are complex I want the button click to open a new window where I can fill in the details, and then return back to the main window.
在我以前的手工方法中，我将 ProfilesCollection 设为静态，以便可以在整个应用程序中访问它，并且在单击事件中，我刚刚打开了一个新窗口，然后将新配置文件存储在静态 Collection 中。
In my previous by hand approach I made the ProfilesCollection static so that it was accessible throughout the whole application, and as click event I just opened a new window, where I then stored the new profile in the static Collection.
正确的MVVM方法是什么？创建一个新的视图/视图模型而不是一个新的窗口？如何管理它们，如何将创建的 Profile 传递回MainViewModel？
What would be the right MVVM approach? Create a new view/ viewmodel instead of a new window? How do I manage them, and how do I pass the Profile I create back to the MainViewModel?
谢谢！
推荐答案
我会先通过 ProfilesCollection 放入 ProfilesViewModel 以及 ProfilesView 来选择所需的配置文件
I would start by passing the ProfilesCollection into a ProfilesViewModel along with a ProfilesView for selecting the profile you want to edit and for adding/removing profiles.
第二，我将有一个单独的 ProfileViewModel 和 ProfileView 。 ProfileViewModel 将具有 ShowDialog 方法，该方法将调用 ShowDialog 在 ProfileView 子窗口中。这将允许 ProfilesViewModel 在 ProfileViewModel 上设置配置文件，然后调用 ShowDialog ，非常适合MVVM模式。
Second, I would have a separate ProfileViewModel and ProfileView. The ProfileViewModel would have a ShowDialog method that would call ShowDialog on the ProfileView child window. This will allow the ProfilesViewModel to set the profile on the ProfileViewModel and then call ShowDialog, which will fit the MVVM pattern nicely.
