please me. once again, want know how child control parent control... possible?

using mvvm pattern, should not referencing of controls directly. alternatively, should create boolean property on viewmodel decides if various controls should visible. bind visibility property of controls want hide property, using converter.

see previous q/a details on visibility converters: link
