WPF MVVM Focus Field on Load

Question

I have a View that has a single TextBox and a couple Buttons below it. When the window loads I want that TextBox to have focus.

Answer 1

1. Have a property in your ViewModel which indicates which is the currently focused element.

2. Use the FocusManager to bind to that property.

Your ViewModel is a translator which exists solely to provide information to the View, so you can add whatever information to the VM that the View needs to function.
