If your application is dealing with objects that have lots of details, use tabbed folders.
Tabs provide a means to logically group large amounts of information and they provide easy navigation.
Be careful where you place command buttons on a tabbed folder: if a button applies to all the tabs, place it outside the tabbed folder so that the button's scope is visually clear. If the button only applies to an individual tab, put it on the tab itself.
Toolbars
You can represent the most common actions for the list items as a toolbar.
