sketch

you have not provided full context of problem, here general steps should take in mvvm application:

  1. use mvvm framework. mvvm light favorite.
  2. inherit viewmodel viewmodelbase (defined in mvvm light).
  3. define both bool value public properties , use raisepropertychanged() tell world change.
  4. bind screens same viewmodel object using standard wpf binding.

now whenever values of bool properties change, screens refreshed automatically.
