Whenever you display a MessageBox and you click on OK you lose focus from your MainWindow. Though logical focus is being saved so when you return back to MainWindow, you see the logical focus which can be turned into keyboad focus when clicking back inside the scope.

To read more about that check this link out.

If you wish to use logical focus and let the wpf do the job for you, then read this:

http://msdn.microsoft.com/en-us/library/System.Windows.Input.FocusManager(v=vs.110).aspx

Now to your question. I would solve this by using FocusManager.FocusedElement. Just set that property inside your error template.

An alternative would be to subscribe to Validation.Error event and force Keyboard.Focus method to focus object sender inside the event handler.
