Question

I had few reading about how to navigate between pages and using the back button.

What I try to do actually is implementing one of my button on the tap event to go back to the previous list box items.

I mean, I bind folders on my listbox. When I click on an item I load the subfolders so the itemssource is changing.

How can I , when i click on the back button, display the previous itemsource of the listbox ?

Should I use history ? Everything is on the same page, so i definitly can’t use this navigate method .

Answer 1

You could hook into the OnBackKeyPress method and alter the ItemsSource, you need to make sure that you can exit your application sucessfully if you went down this route :-
