-

with 2 booleans (bool 1, bool2) changing between 4 screens/usercontrols (over ipageviewmodel class). every usercontrol connected viewmodelbasescreens class. above have 1 main screen in lying 2 booleans can change screen.

every of screen have same boolean synchronized between screens. how update boolean between usercontrols? or how bind @ same time (when property change)? best solution?

i transfer bool value between screen user set in previous screen.

i pretty beginner in wpf (mvvm) please gentle me :)

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.
