Расширитель Modalpopup внутри другого расширителя modalpopup

---

gridview1 внутри modalpopupextender1 с помощью кнопки linkbutton открывает другой modalpopupextender2 с помощью gridview2.
теперь, когда я нажимаю кнопку linkbutton gridview1, которая находится внутри modalpopextender1.... modalpopupextender2 не всплывает ...и даже не показывая никаких ошибок...это просто когда я проверяю элемент в браузере, и он говорит

"

206|error|500|ERROR [HY000] [MySQL][ODBC 3.51 Driver]Access denied for user 'ODBC'@'localhost' (using password: YES)

"

Мой файл webconfig:

<add name="connect3" connectionstring="DRIVER={MySQL ODBC 3.51 Driver};  Host=localhost;UserName=root;Password=*****;Database=welco1_all" />
      <add name="connect4" connectionstring="DRIVER={MySQL ODBC 3.51 Driver}; SERVER=localhost; UID=root; PASSWORD=12345; OPTION=3" />

Я перепробовал почти все ...но ничего хорошего не приходит...любая помощь высоко ценится...

Что я уже пробовал:

Это мой HTML файл:
