DragDrop registration failed

[michael wikstrom]

I get this error "DragDrop registration failed" when setting the AllowDrop property in a control. Im accessing a control from a different thread than the one that created the control. I use invoke when adding and removing,, the problem is i dont know if i have to invoke the dragdrop event or how it should be done.

Drag and drop registration must be performed on the STA thread, so it must be called from the thread on which the control was created. If you're setting the AllowDrop property from a different thread, use Invoke for that as well, getting the get accessor using Reflection and creating a delegate that matches the signature. Call Control.Invoke using that delegate that references the get accessor method.
