Вот небольшой пример проекта, показывающий, как я это сделал. Он основан на разных ответах, которые я нашел в основном на переполнении стека.
Хитрость заключается в том, чтобы использовать @Html.Raw
и испускать атрибут checked
только при выборе элемента. Настройка checked="false"
не будет работать!
