If you're wondering how to do it in a nice way, then I would say that you're looking something a long of the lines:

where MouseButtonMoved is an attached property (of type ICommand) that hooks itself into the ItemsControl MouseButtonMove event, and then executes the the command it is binded against, passing two double values (x, y) through the MouseButtonMoved.Execute(x, y).

If you want to see similiar implementations, check for gongdrop implementation. I'd use that as a solution, but if you want to rewrite it from zero, just read the source.
