Функция редактирования строк Gridview не работает

---

У Gridview есть 10 записей, и я собираюсь отредактировать 5-ю строку, когда она появится на edit click, но другие 5-10 записей не появятся(привязка)..

Я следую за столькими статьями, все еще одинаковыми только для того, что я написал код точно.

Пожалуйста, подскажите мне точное решение.
