   // TODO: Refresh your data
}

void MainPage::InitHandlers()
{
    Windows::Storage::ApplicationData::Current().DataChanged({ this, &MainPage::DataChangeHandler });
}

void MainPage::DataChangeHandler(Windows::Storage::ApplicationData const& /* appData */, Windows::Foundation::IInspectable const& /* object */)
{
    // TODO: Refresh your data.
}

void MainPage::InitHandlers()

   Windows::Storage::ApplicationData::Current->DataChanged += 
      ref new TypedEventHandler<Windows::Storage::ApplicationData^, Object^>
      (this, &MainPage::DataChangeHandler);
}

void MainPage::DataChangeHandler(Windows::Storage::ApplicationData^ appData, Object^)
{
   // TODO: Refresh your data
}

Private Sub InitHandlers()
