This is carried out in the toolbar. If you delete an adapter that has been saved previously, its State is set to Deleted, and its row text color set to red. You may no longer select a deleted row. If you delete an adapter that is yet to be saved, it is removed from display. You can delete multiple adapters concurrently. Delete is not protected by an ‘Are You Sure’ dialog. You cannot delete an adapter that is associated with one or more channels.
