WPF-MVVM: Setting UI control focus from ViewModel

Question

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

The way I envision it, is with a property on the ViewModel that would trigger a focus change

Answer 1

Use the IsFocused Attached Property as suggested in the Answer here: Set focus on textbox in WPF from view model (C#)

Then you can simply bind to a property in your viewmodel.
