Никакая перегрузка для системы "InsertButton_Click" не соответствует системе "делегат".EventHandler' [ошибка]
Почему моя обработка событий не работает? Я получаю эту ошибку. Я использую VS 2008 / .NET 3.5 SP1 / Win XP, и, на всякий случай, исходный код доступен здесь.
Ошибка 1 отсутствие перегрузки для системы "InsertButton_Click" соответствует системе "делегат".EventHandler' c:\inetpub\wwwroot\Jon ' S Couch\Articles. aspx. cs 21 31 http://localhost/Jon кушетка/
