Кнопка не остается отключенной после повторной загрузки формы ⇐ C#

[Anonymous]

Я создаю систему бронирования мест для проекта колледжа. Итак, у меня есть этот код, и если пользователь выберет кнопку/место и нажмет кнопку записи, он запишет это место в текстовый файл. Но если я закрою форму и загружу ее снова, кнопка не останется отключенной, и я не пойму, в чем дело.
