Hiding a button on pushed view and showing it when back to list view?

I'm not sure whether this is the best approach or not but if I were you I will use the back event of navigation view which fired when you tap the back button.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
