Я переписываю стиль для PhoneTextBox, меняя фон по умолчанию на «Transpanrent», передний план на «White» и BorderBrush на «White», потому что я хочу создать Dark-Theme.
Но возникла проблема, что индикатор ввода текста исчез. Я благодарен за то, что передний план индикатора ввода текста черный, поэтому пользователь не может его видеть. Но я не могу найти способ определить передний план индикатора ввода текста. Любые советы будут оценены.
PS. Я не знаю, как описать индикатор, поэтому я составляю слово «индикатор ввода текста», как показано ниже:
Нормальная ситуация, появляется черная вертикальная линия.
После переписывания стиля пользователь не может видеть черную вертикальную линию:
