Handling Back Navigation Windows 10 (UWP)

Question

In my Xaml Page I\'ve got a Frame.

I\'m trying to have a backButton event to just navigate inside frame .

so I tried to use this piece of code

Answer 1

I think this is because you add HardwareButtons_BackPressed in your page instead on in app.xaml.cs.

In app.xaml.cs :

public App()
{
    this.InitializeComponent();
    this.Suspending += this.OnSuspending;

    HardwareButtons.BackPressed += HardwareButtons_BackPressed;
}

void HardwareButtons_BackPressed(object sender, BackPressedEventArgs e)
{
    Frame rootFrame = Window.Current.Content as Frame;

    if (rootFrame != null && rootFrame.CanGoBack)
    {
        e.Handled = true;
        rootFrame.GoBack();
    }
}

Now, back button of your phone will work on any pages.

And then, if you want to add a particular button doing back in any page :

In the particular page (or each pages if you want) :

public void btn_return_Tapped(object sender, TappedRoutedEventArgs e)
        {
            Frame rootFrame = Window.Current.Content as Frame;

            if (rootFrame != null && rootFrame.CanGoBack)
            {
                e.Handled = true;
                rootFrame.GoBack();
            }
        }
