How to keep WPF TextBox selection when not focused?

Question

I want to show a selection in a WPF TextBox even when it\'s not in focus. How can I do this?

Answer 1

I found that the suggestions listed (add a LostFocus handler, defining a FocusScope) to not work, but I did come across the code listed here: http://naracea.com/2011/06/26/selection-highlight-and-focus-on-wpf-textbox/, which creates a custom Adorner that highlights the text when not focused.
