Я использую datagrid и используя команду Edit link. Я предполагаю взять новые значения в команде rowUpdating и запустить ее в базу данных. Но я получаю только старые ценности. Я написал другую страницу с небольшой функциональностью, и она работает нормально. Я могу понять, что не так с моим кодом. Я размещаю код ниже.gridview rowupdating возвращает старые значения
