Thanks Bonnie,
It works. What I don't understand (I mean: if I really do something wrong or it's VS that work in a such way) is that sometimes it's seems that the code IS there, but it doesn't fire.
It's happened when I moved controls on a form, for example moving a button from the form itself into a panel o a tabcontrol make the button click event's code not fire.

I do it from the ItemDrag eventhandler ... there should be something comparable for the PictureBox, or (since I don't see anything obvious there), you could probably fire a DoDragDrop() method from the DragEnter eventhandler.
