通信的两个视图模型在WPF MVVM [英] Communicate two view models in WPF MVVM
问题描述
我开发一个WPF应用程序，我有一些问题相互通信一个视图模式。
I am developing a WPF application and I have some problems to communicate one view model with another.
我有：
- MainViewModel
- ChildViewModel1
- ChildViewModel2
每一次在MainViewModel，ChildViewModel1和ChildViewModel2属性变化应该得到通知。
Every time a property changes in MainViewModel, ChildViewModel1 and ChildViewModel2 should get notified.
任何人都可以提出一个解决办法？
Can anyone suggest a workaround?
编辑：
我想在一个解决方案descrided MVVM光（<一个href=\"http://simplemvvmtoolkit.$c$cplex.com/SourceControl/changeset/view/23821#313594.\">http://simplemvvmtoolkit.$c$cplex.com/SourceControl/changeset/view/23821#313594.),正在实施的消息总线，它是正确的做法？
I am thinking in a solution descrided MVVM Light (http://simplemvvmtoolkit.codeplex.com/SourceControl/changeset/view/23821#313594.), that is implementing a message bus. Is it the right approach?
推荐答案
有关的ViewModels之间进行相互沟通的常见方式
是theMediator设计模式的执行力度。
the common way for viewmodels to communicate between themselves is implimentation of theMediator design pattern
