[C#] how do I implement a completely custom draggable control?

I guess I didn't need the [C#] qualifier in a C# forum lol.

I work on an application that requires some fancy custom controls. Inheriting from the .net Control class has caused various problems and is making things harder as time goes on. I won't get into the specifics here, but I am creating my own light weight control architecture to avoid some of these problems. Things art working nicely, but I need to add drag and drop functionality into my architecture.

All of the methods that I have come up with so far seem messy and error prone. I am mimicking the .net Control class in many ways, and have used the .net reflector to great benefit, but I am having a problem figuring out how to make my drag events fire (DragDrop, DragEnter, DragLeave).

I just can't think of a clean way to fire off these events. Does anyone have any ideas?
