I’m building a WPF navigation app, with pages.
I want to ask the user if he want to save the changes when he leaves a page.
Is there a way to do it?

Register for the
NavigationService.Navigatingevent. Don’t forget to remove your registration when you are done, sinceNavigationServicesticks around basically forever.When you get the Navigating event and there are changes, show a MessageBox to confirm with the user or give them a chance to save their data. If they hit Cancel, set
e.Cancel = trueto cancel the navigation.
