The reason you cannot (yet) edit it directly (evidently) is you probably haven't authored properties which interface the composite control you have built. It's commendable you have gotten that far, actually. That's pretty good. What I had in mind as sharing controls for all your pages -- in other words, use one set of controls built into your page control, and focus those on material of the focused/active page. That's just an alternate suggestion, and it is only pertinent if it would suit your purposes. But it is the most efficient way to go, because instead of deploying many controls, each of which do a given thing with given objects of one page, each of those controls is focused on the objects of the whatever number of pages... one page at a time of course, with the one page being the focused page.
