Question

What is the best approach in passing a complex object between Pages in a Windows Store App? In the MSDN it states that only basic types of objects can be passed in order to serialize the session state, but I don’t intend to serialize session state since my app will just log out and ask for log in credentials when the app is launched the next time. I plan to serialize my data when the user either hits the log out or save buttons.

Let’s say that you are passing a Person object to the PersonDetailPage. Then here is what you would have on your MainPage (or any other page).

Assuming that you are working with a GridView:

this.Frame.Navigate(typeof(PersonDetailPage), (Person)e.ClickedItem);

Then on the PersonDetailPage, on the LoadState() you will verifiy if a parameter was passed, and then atribute that parameter to a variable.

protected override void LoadState(Object navigationParameter, Dictionary<String, Object> pageState)
{
      if (navigationParameter != null)
      {
           person = (Person)navigationParameter;
      }
}
