问题
I want to forward the mouse scroll event from a control to its direct parent (which is also UserControl in my case).
How is this possible?
Edit The control is added to a control that is scrollable. Like a memo-edit for example.
When the user scrolls in the memo-control, the memo-control is scrolled (!) But when the user scrolls on top of the custom control the event is not forwared to the parent control and the memo-control does not scroll.
