Application with two windows

Question

I have WPF app with 2 windows - whats the best way to syncronise 2 windows hide/toggle/show ? i.e. if hidden both must be hidden, if restored both must be restored.

thanks.

Answer 1

Do they both in the same project and under the same scope?
if so it's simple just bind there WindowState together.

on both onLoad and StateChanged check if the other window already has state and match their WindowState property.

you can see about StateChanged in this link:
Window StateChanging event in WPF
