Question

I can’t figure out why this isn’t working?!

        protected void Submit_Click(object sender, EventArgs e)
    {
        Update();
    }

    public void Update()
    {
        try
        {
            using (SqlConnection conn =
                new SqlConnection(conStr))
            {
                conn.Open();
                using (SqlCommand cmd =
                    new SqlCommand("UPDATE DriverInfo SET FirstName=@NewFirstName, LastName=@NewLastName, Age=@NewAge, Country=@NewCountry, Town=@NewTown WHERE UserId=@Id", conn))
                {
                    cmd.Parameters.AddWithValue("@Id", currentUserId);
                    cmd.Parameters.AddWithValue("@NewFirstName", tbfirstname.Text);
                    cmd.Parameters.AddWithValue("@NewLastName", tblastname.Text);
                    cmd.Parameters.AddWithValue("@NewAge", tbage.Text);
                    cmd.Parameters.AddWithValue("@NewCountry", tbcountry.Text);
                    cmd.Parameters.AddWithValue("@NewTown", tbtown.Text);

                    int rows = cmd.ExecuteNonQuery();

                    //rows number of record got updated
                }
            }
        }
        catch (SqlException ex)
        {
            //Log exception
            //Display Error message
        }
    }

This should be a page where the logged in user can change his settings and them should be updated in the database.

Answer 1

The only thing that I can see from the code given and with no exceptions is that the @Id may not be set right or not be equal to any existing Id’s in the current table.
