В страницу вставил GridView, связал с SQLDataSource. Настроил все и получаю все данные как полжено. Sorting, paging, edit, delete, update, insert работает без проблем. Переключаюсь в код за форму, там пусто. Где вся это реализация скрывается?

P.S. В Windows Form проектах смотрел все это нажимая кнопку "Show All Files". В веб-проектах эта кнопка недоступна.

Ткните пальцем, где тут реализация сортировки или постраничного вывода? Где процедура, выполняемая например при нажатии edit, update?
