如何从不同的ViewModels修改数据网格 [英] How do I modify a datagrid from diffrent ViewModels

问题描述

我有一个包含多个UserControl的视图。每个UserControl都有一个ViewModel。 ViewModel继承自baseViewModel，它实现了INotifyPropertyChanged的东西。

其中一个viewmodel包含一个datagrid，另一个包含一个textbox和一个apply按钮。独立一切都很好。但我想从其他ViewModel的列表中的文本框中应用输入的数字。



有没有人有一个虚拟的友好解释来实现这个目标？

我应该使用哪种方式？ No1直接通信ViewModel1< - > ViewMode2或No2 ViewModel1< - > Model< - > ViewModel2

I have a View with multiple UserControls. Each UserControl has its one ViewModel. The ViewModels inheritances from a baseViewModel, which implements the INotifyPropertyChanged stuff.
One of the viewmodel contains a datagrid and another has a textbox and an apply button. Independently everything is working fine. But I would like to apply the entered number from the textbox in the list from the other ViewModel.

Does anyone have a dummy friendly explanation to achieve this?
