سلام من میخوام در یه gridview ببا استفاده از SqlDataSource به صورت کد اطلاعاتی رو قرار بدم، میدونم به صورت ویزاردی راحت میشه SqlDataSource vرو مقدار دهی کرد ولی من نیاز دارم این کار رو با کد انجام بدم من یه شی ساختم از SqlDataSource و از روی پراپرتی یه SqlDataSource دیگه که ویزاردی ساختم به SqlDataSource خودم مقدار دهی کردم به صورت زیر :



SqlDataSource s = new SqlDataSource();

        s.ConnectionString = "Data Source=.;Initial Catalog=MYDB;Integrated Security=True";

        s.ProviderName = "System.Data.SqlClient";

        s.ID = "SqlDataSource2";

        s.SelectCommand = "SELECT * FROM [tblUser]";



        GridView2.DataSourceID = "SqlDataSource2";


اما بعد از اجرا ارور زیر رو میگیرم .
کد HTML:
Server Error in '/test2' Application.
