У меня есть пользовательский элемент управления, и в этом пользовательском элементе есть элементы управления ui, такие как кнопка и список, у меня есть прикрепленные клики и выбор изменений событий этих элементов управления от xaml, а также попробовал их с программным обеспечением, но события не запускаются.

любого рода помощь будет оценена, Большое спасибо
