По умолчанию реализация ExpanderView в приложении отображает пользовательский интерфейс, а элемент управления expanderView имеет это левое поле, применяемое к нему, какой-то отступ. Это довольно глупо, что по умолчанию это похоже.
Есть ли какой-то способ избавиться от этого поля и просто чтобы плавающий элемент управления полностью находился влево?
Также, как добавить текст в прямоугольник расширителей? Нет такого имущества.
Вам просто нужно отредактировать контрольный шаблон для Expander. Если у вас есть Expression Blend, это делает его быстрым и легким. Вы просто щелкните правой кнопкой мыши на расширителе на монтажной панели, выберите "Редактировать шаблон", а затем выберите либо отредактировать текущий, либо копию, которую вы могли бы сделать, и, возможно, поместить в отдельный словарь ресурсов. Вот пример шаблона. Обратите внимание на марку 11,0,0,0 на элементахCanvas в нижней части?. Вы можете использовать этот же метод для редактирования практически любого шаблона управления.:)

В любом случае, как только вы найдете шаблон управления быстрым и безболезненным. Надеюсь, это поможет!
Поздно, но, возможно, это поможет кому-то. Я удаляю эту маржу в этом стиле. Я удалил столбцы из сетки по умолчанию. Более того, я создаю его как панель Wrap. Его можно изменить в ItemsPanelTemplate.
