Controlはnullのままですよ。
Dispatcher.AcceleratorKeyActivated と Control は関係ありません。
今の実装 ↓
protected override void OnElementChanged(ElementChangedEventArgs<Page> e)
{
base.OnElementChanged(e);
if (e.OldElement != null)
{
Dispatcher.AcceleratorKeyActivated -= Dispatcher_AcceleratorKeyActivated;
imgView = null;
}
if (e.NewElement != null)
{
imgView = (ImageView)e.NewElement;
Dispatcher.AcceleratorKeyActivated += Dispatcher_AcceleratorKeyActivated;
}
}
private void Dispatcher_AcceleratorKeyActivated(Windows.UI.Core.CoreDispatcher sender, Windows.UI.Core.AcceleratorKeyEventArgs args)
{
if (args.EventType == Windows.UI.Core.CoreAcceleratorKeyEventType.KeyDown)
{
if (imgView != null)
{
imgView.OnKeyDown(args.VirtualKey);
}
}
}
