WPF RoutedEvents Being Handled By...?

Question

I have a 3D application in WPF which basically is supposed to zoom in and out as the MouseWheel event is fired. I have attempted to subscribe everything possible, but can't find what it is which is handling it.

Is there a way to find out what is? Or is there a way to have the event not handled, or for an encompassing UIElement to get to this event before/after the one dealing with it?

Answer 1

If you want to get called even though someone else has already handled the event, try subscribing to the event using the UIElement.AddHandled(RoutedEvent, bool) function. Pass in true as the second argument to get called even if the event has been handled.

You can also try subscribing to the PreviewMouseWheel event to get called when the event is tunneling.
