UserControl Drag n Drop Snag

Hi,
I can dragdrop my custom control anywhere on the form as long as I move it a fair distance. If I try moving it a little bit, then of course it drops back to where it began.

I understand I can remedy that by adding a Dragdrop event to my usercontrol using RaiseEvent and Public Event lines. I can do that except that for the following complications.

1. My control only has shapes which does not support dragdrop events.
2. So, I put all of these shapes in a picture box because this box has the dragdrop event.
3. I do everything correctly, but there is one major snag.

Apparently, I cannot pass a Private Control Source such as a picture box control in my user control to a public event. I can add mousedown events okay because it does not pass the private control source.

This is the final step to my pneumatic cylinder control functioning fully.

I appreciate any input.
Thanks,
