Difference between registering an event handler in XAML and in C++ file

Question

In a Direct2D+XAML app, some event handler functions are registered in DirectXPage.xaml

    <SwapChainBackgroundPanel x:Name="SwapChainPanel"  PointerMoved="OnPointerMoved" PointerReleased="OnPointerReleased">

I guess we can also register the same event handler functions in C++ file DirectXPage.xaml.cpp

    Window::Current->CoreWindow->PointerReleased +=
        ref new TypedEventHandler<CoreWindow^, PointerEventArgs^>(this, &DirectXPage::OnPointerReleased);

So what's the difference between the two methods?

Answer 1

There aren't really any difference except what element you are listening to event on. In you XAML case you are listening to Pointer events on SwapChainPanel, and in the other case you are listening to events on the core window / root element. If you wanted to make them the exact same, use SwapChainPanel->PointerReleased instead of CoreWindow.
