mvc пропустить элемент Max, если элемент Min пуст

Question

Работа над MVC5 c # Entity Framework Project, в котором пользователь вводит серию значений 40 мин / макс. Пользователь хотел бы, чтобы TAB пропустил файл Max, если поле Min не заполнено или не имеет значения null, и перейдите к элементу Next Min. Это поведение в текущем приложении, которое мы конвертируем в MVC / Entity Framework, и оно, если возможно, хотело бы воспроизвести это поведение.

Пример кода содержит 3 столбца на строку полей Min / Max. Порядок табуляции находится внизу столбца и использует tabindex в операторе EditorFor, чтобы заставить работать порядок табуляции.

Мы просто хотим, чтобы он пропустил файл Max и перешел к следующему полю Min, если это возможно. Спасибо за любую помощь или направление.
