Проблема с шаблоном MessageBox

Question

У меня есть этот шаблон для MessageBox. Я изменил так, что у вас может быть полоса прокрутки, единственная проблема, с которой я сейчас сталкиваюсь, заключается в том, что заголовок очень отделен от сообщения, и я не знаю, как их объединить. Попробуйте все, но я не могу.

Answer 1

Вы должны установить свойство Height _plHeader

Если вам необходимо изменить высоту динамически вы можете использовать Graphics.MeasureString, TextRenderer.MeasureText или auto resize TextBox, чтобы получить требуемую высоту панели
