When using standard Delphi components, the settings for a component that acts as a Docksite can be savedusing the Dockmanager. That works on a TAdvPanel too. I can save and restore the settings of its Dockclients using AdvPanel.DockSite.SavetoStream.
When using TAdvPageControl the docking / undocking works as expected, but I can't save it, because Docksite is always nil. What can I do to save the settings for a TAdvPageControl?
Never mind, this has nothing to do with TAdvPagecontrol, in the standard TPageControl its the same. The property UseDockManager is not visible in the IDE, it has to be set manually. That works.
