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？
推荐答案
使用的IsFocused附加属性在这里回答提示：的
Use the IsFocused Attached Property as suggested in the Answer here: Set focus on textbox in WPF from view model (C#) & wPF
然后，你可以简单地绑定到您的视图模型的属性。
Then you can simply bind to a property in your viewmodel.
