hi!!!
i have a problem.. i am using viaual studio 2010 and i can insert data but i can't UPDATE & DELETE. The visual studio says this error: Incorrect syntax near 'Index'. If this is intended as a part of a table hint, A WITH keyword and parenthesis are now required. This is the code that i am using for the UPDATE command:

C#

da.UpdateCommand = new SqlCommand("UPDATE Studenti SET  ime = @ime, prezime = @prezime WHERE Index = @Index",cs);
            da.UpdateCommand.Parameters.Add("@ime", SqlDbType.VarChar).Value = txtVnesiIme.Text;
            da.UpdateCommand.Parameters.Add("@prezime", SqlDbType.VarChar).Value = txtVnesiPrezime.Text;
            da.UpdateCommand.Parameters.Add("@Index", SqlDbType.Int).Value = ds.Tables[0].Rows[studentiBS.Position][0];
            cs.Open();
            da.UpdateCommand.ExecuteNonQuery();
           cs.Close();

i have searched on the net but i cant find the answer. please help

Error lies here.
You are tring to assign an object to int type parameter.

Try:

C#

da.UpdateCommand.Parameters.Add("@Index", SqlDbType.Int).Value = Convert.ToInt32(ds.Tables[0].Rows[studentiBS.Position][0].ToString());
