    Assign an instance of this class to the control's CreationFilter property:
    public class GroupLineRemoverCreationFilter : IUIElementCreationFilter
    {
        public GroupLineRemoverCreationFilter()
        {
        }

        void IUIElementCreationFilter.AfterCreateChildElements(UIElement parent)
        {
            UltraListViewGroupUIElement groupElement = parent as UltraListViewGroupUIElement;
            if ( groupElement != null )
            {
                UltraListViewGroupHeaderLineUIElement lineElement =
                    groupElement.GetDescendant( typeof(UltraListViewGroupHeaderLineUIElement) )
                    as UltraListViewGroupHeaderLineUIElement;

                if ( lineElement != null )
                    groupElement.ChildElements.Remove( lineElement );
            }
        }

        bool IUIElementCreationFilter.BeforeCreateChildElements(UIElement parent)
        {
            return false;
        }
    }
