W poniższym przykładzie kodu pokazano, jak utworzyć obiekt DesignerActionItemCollection i wypełnić go w celu utworzenia listy tagów inteligentnych. Ten przykład kodu jest częścią większego przykładu podanego DesignerActionItem dla klasy.

public override DesignerActionItemCollection GetSortedActionItems()
