Я пытаюсь выполнить двустороннее связывание, например, у меня есть кнопка (из многих элементов управления), при ее выборе я показываю значения ее свойств diff (таких как высота, ширина и т. Д.) В некотором текстовом вводе.Этот односторонний процесс работает нормально.
Но обратный процесс не работает.т.е. когда я выбираю какую-то кнопку и пытаюсь изменить ее размер, вводя какое-то значение в тексте по высоте, ширине, размер не изменяется.
Как узнать, какая кнопка была выбрана мной?Как события должны быть обработаны здесь?
