Is it possible for a group to contain both UltraExplorerbarItems and a custom control?
I am dynamically creating my groups and items from data in the DB. I also have a custom user control that controls the styling of the explorerbar. I need to be able to create a group that supports the combination of UltraExplorerbarItems and my custom user control.
No, it does not support both items and control containers. Note that you could use an UltraListView for the items, then extend your UserControl to include that control.
