PreviewKeyDown for Windows Store App ListBox

Question

Is there an equivalent to the PreviewKeyDown for a Windows Store App? It isn\'t available.

I have exactly the same problem as described her

Ah, tricky. Handling key events isn't super-obvious. Here's what you want:

public MainPage()
{
    this.InitializeComponent();
    Window.Current.CoreWindow.Dispatcher.AcceleratorKeyActivated += (s, args) =>
    {
        if ((args.EventType == CoreAcceleratorKeyEventType.SystemKeyDown 
            || args.EventType == CoreAcceleratorKeyEventType.KeyDown)
            && (args.VirtualKey == VirtualKey.Up))
        {
            MoveUp();
        }
        else if ((args.EventType == CoreAcceleratorKeyEventType.SystemKeyDown 
            || args.EventType == CoreAcceleratorKeyEventType.KeyDown)
            && (args.VirtualKey == VirtualKey.Down))
        {
            MoveDown();
        }
    };
}

private void MoveUp()
{
    // this part is up to you
    throw new NotImplementedException();
}

private void MoveDown()
{
    // this part is up to you
    throw new NotImplementedException();
}

Best of luck!
