Я использую элемент управления сеткой в своем веб-приложении. Мой вид сетки выглядит следующим образом.как добавить больше контроля в каждую ячейку редактируемого gridview с помощью asp.net
При нажатии на кнопку Add я получаю результат, как это ..
Но мой ожидаемый результат это один .. где моя ошибка? что мне делать?
Это мое кодирование ..

, как любой человек может сказать не глядя на свой код? –
укажите коды .. у нас нет способа узнать, что вы делаете за добавлением события –
@Mathi, вы имеете в виду, что введенные значения исчезают при нажатии кнопки «Добавить» ... Правильно? и это ваша проблема ... правильно? –
