C# Winforms 3.5

I have a list of user controls all derived from one base class. These controls can be added to various panels and I'm trying to implement the drag-drop functionality, the problem I'm running in to is on the DragDrop event.

The DragEventArgs: e.Data.GetData(typeof(baseClass)) doesn't work. It wants:

e.Data.GetData(typeof(derivedClass1))
e.Data.GetData(typeof(derivedClass2)) etc...

Is there a way I can get around this, or a better way to architect it?

The dynamic type in C# 4.0 is a welcome addition to the language.

In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
