Конференция ".Net" » dataGrid1 после компиляции проекта пустой [C#, WinXP]

    С праздником всех!
    что я делаю не так
    1) создал проект ASP.Net
    2) размещаю sqlConnection1, устанавливаю ConnectionString=user id=sa;data source=vipr;persist security info=True;initial catalog=pubs;password=7777777
    3)размещаю sqlDataAdapter1 и устанавливаю CommandText=select * from authors, в контекстном меню выполняю Generate Dataset
    4) размещаю dataGrid1 в свойстве DataSet=dataSet11, DataMember=Table
    5) ввожу
    dataGrid1.DataSource=dataSet11;
    dataGrid1.DataBind();
    в private void Page_Load(object sender, System.EventArgs e)
    Компилирую, выводится IE7 с пустым dataGrid, в таблице данные есть, а на экране нет.

    Далее указываю полный код проекта:

    А где, собственно, заполнение DataSet?
