переключатель в поле шаблона сетки

Я делаю веб-приложение для экзамена в ASP.NET. Я использую grid-view для отображения вопроса и возможных ответов. Я задал размер сетки - 1, поэтому он отображает только один вопрос на индекс страницы. Я использую переключатель для выбора нескольких вариантов.переключатель в поле шаблона сетки

Когда я выбираю радиокнопку и перехожу к следующему типу или следующей странице индекса сетки и снова возвращаю предыдущий вопрос, тогда я вижу, что переключатель, который я выбрал ранее, не выбран. Что я должен сделать для этого?
