Navigation without creating a new page instance

[zelo66]

Hey, I have one problem.

How can I use the NavigationView without creating a new instance of the page?
Im using NavView with "ItemInvoked" event andframeto display the page.
This leads to problems such as the loss of data when Navigate is performed in different pages using simple data binding.
So, is there any way to save page.Content and replace only the page.Content when Navigate, thus achieving page persistence?

Thanks.
