Have a look at the default code created when you start a new DataBound Project. It shows a way of passing a reference to a selected object to a details page.

Answer 3

Using OnNavigatedFrom method

OnNavigateFrom is called when we call the NavigationService.Navigate method. It has a NavigationEventArgs object as a parameter that returns the destination page with its Content property with which we can access a property of the destination page "DestinationPage.xaml.cs"

First, in the destination page "DestinationPage.xaml.cs", declare a property "SomeProperty":

public ComplexObject SomeProperty { get; set; }

Now, in "MainPage.xaml.cs", override the OnNavigatedFrom method:

protected override void OnNavigatedFrom(NavigationEventArgs e)
{
// NavigationEventArgs returns destination page "DestinationPage"
    DestinationPage dPage = e.Content as DestinationPage;
    if (dPage != null)
    {
        // Change property of destination page 
        dPage.SomeProperty = new ComplexObject();
    }
}

Now, get the SomeProperty value in "DestinationPage.xaml.cs":

private void DestinationPage_Loaded(object sender, RoutedEventArgs e)
{
    // This will display a the Name of you object (assuming it has a Name property)
    MessageBox.Show(this.SomeProperty.Name);
}
