MaintainScrollPositionOnPostback не работает, когда я нажимаю кнопку редактирования

Question

Я использую asp: GridView внутри asp: Panel на странице asp: Content.GridView имеет более 100 строк, поэтому я использую Panel для вертикальной полосы прокрутки.Я установил MaintainScrollPositionOnPostBack = "True" в обеих директивах <% @ Page%>, но GridView переходит прямо вверх, когда пользователь выбирает одну из строк.Что я делаю не так?

Спасибо,

, это мой код для сетки
