I'm working on an UniversalApp using the Library Prism. My App.cs inherit MvvmAppBase so it will handle automatically the back pressed event and this is the problem because I have some cases in my app when the user press on back button it will show him a Message Box for example.
I tried to handle the event back press on my App.cs but the problem is still persist, the page go back in all cases. I want to block the page and not GoBack.
I have found a solution that say to implement a new interface INavigateBackwards but I don't have an idea what should I add on this new interface.
I think many developers who work with prism already faced the same problem so can anyone help me for this issue?
Thank you.
