如何在WPF MVVM中实现ViewModel之间的通信 [英] How to achieve communication between ViewModels in WPF MVVM

问题描述

HI，
在我看来，我有一个DataGrid和一个用户控件，它们都使用两个不同的ViewModel.我的用户控件还包含一个DataGrid.当我在任一ViewModel的DataGrid中添加新行时，它应通知另一个ViewModel或更好地将新添加的DataRow传递给另一个ViewModel.我该如何实现.

谢谢与问候，
Ramana

In my view I have a DataGrid and a usercontrol, both are using two different ViewModels. My user control also contains a DataGrid. When I add a new row to my DataGrid in any one of the ViewModel, it should notify the other ViewModel or better pass the newly added DataRow to the other ViewModel. How can I achieve this.

Thanks & Regards,
Ramana

推荐答案

您可以使用Marlon的 EventAggregator [^ ]来自Microsoft的PRISM框架.如果您使用Google for Mediator/EventAggregator，会获得大量使用示例.

You could use Marlon''s Mediator[^] or EventAggregator[^] from Microsoft''s PRISM Framework. If you Google for Mediator/EventAggregator you get loads of samples on how to use them.
