No events passed to WPF adorner layer?

I don't know if you already tried that: If you want the element added to react to events, I think that the element must be bound to the visual tree of the adorner. The way to do it is to use a VisualCollection intitialized to the adorner itself, or at least, this way it seems to be working.

Add(@object); } protected override Visual GetVisualChild(int index) { return visualChildrenindex; } This way the events are correctly routed.

Thanks a lot! It works – 6opuc Sep 29 at 3:49.

I just had the same issue. Following the advice from MSDN sorted it for me: Adorners receive input events just like any other FrameworkElement. Because an adorner always has a higher z-order than the element it adorns, the adorner receives input events (such as Drop or MouseMove) that may be intended for the underlying adorned element.An adorner can listen for certain input events and pass these on to the underlying adorned element by re-raising the event.

To enable pass-through hit testing of elements under an adorner, set the hit test IstTestVisible property to false on the adorner. I. E In the adorner itself, make sure IstTestVisible = false.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
