WPF的MVVM：从视图模型设置UI控件焦点 [英] WPF-MVVM: Setting UI control focus from ViewModel

问题描述

什么是MVVM架构设置控制的重点一个很好的做法。

What is a good practice of setting control focus in MVVM architecture.

我想象它的样子是在视图模型的属性需要时，将触发焦点变化。比有控件绑定/用户界面听那个属性，因此，如果它的变化，适当的焦点将被设置。

The way I envision it, is with a property on the ViewModel that would trigger a focus change when needed. And than have the UI controls bind/listen to that property so that if it changes, appropriate focus will be set.

我认为这是一个ViewModel的事情，因为我想成立后，由视图模型执行特定操作，如加载某些数据集中适当的。

I see it as a ViewModel thing, because i want to set focus appropriate after a certain action was performed by the ViewModel, such as loading certain data.

什么是最好的做法？
