My c# code goes thorough all if statements although all of them are false

I have an attendancesheet program. I have triple checked my database tables all of their columns are null. I said if they are not null go through but although all of them are null it goes through them all :D I dont know whats wrong

           private void textBoxX1_KeyDown(object sender, KeyEventArgs e)
    {

        sqlcon.Close();
        sqlcon.Open();
        if (e.KeyCode == Keys.Enter)
        {
            string t = lbl_Time.Text;
            string d = lbl_Date.Text;

            string selectQueryName = "SELECT name FROM tbl_attendanceMembers where memberCode=" + "'" + textBoxX1.Text + "'";
            var sqlcmdName = new SqlCommand(selectQueryName, sqlcon);
            var resultName = sqlcmdName.ExecuteScalar();

            string selectQueryId = "SELECT MAX(id) FROM tbl_attendanceSheet";
            var sqlcmdId = new SqlCommand(selectQueryId, sqlcon);
            var resultId = sqlcmdId.ExecuteScalar();
            (1)if (resultId != null)
            {
                string selectQueryCockin = "SELECT Clockin FROM tbl_attendanceSheet where id=" + resultId;
                var sqlcmdCockin = new SqlCommand(selectQueryCockin, sqlcon);
                var resultCockin = sqlcmdId.ExecuteScalar();
               (2)if (resultCockin != null)
                {


                    (3)if (resultName != null)
                    {

                        this.lbl_mmbrname.Text = resultName.ToString();
                        this.lbl_timestored.Text = t;
                        textBoxX1.Clear();

                    }

                }
            }
            else //if result id == null
            {
                sqlcon.Open();
                SqlCommand sqlcmdClockin = new SqlCommand("InputClockIn", sqlcon);
                sqlcmdClockin.CommandType = CommandType.StoredProcedure;
                sqlcmdClockin.Parameters.AddWithValue("@InputDate", d);
                sqlcmdClockin.Parameters.AddWithValue("@InputTime", t);
                sqlcmdClockin.ExecuteNonQuery();
                SqlDataAdapter sqlda = new SqlDataAdapter("SELECT * FROM tbl_attendanceMembers", sqlcon);
                DataTable dt = new DataTable();
                sqlda.Fill(dt);
                dataGridView1.DataSource = dt;
            }

            sqlcon.Close();

        }

when I execute this code,it equals lbl_mmbrname.Text to resultName and lbl_timestored.Text = t. so it means it has gone through all the way down into the 3rd if statement which is false... I have check it via break poits(f9).

by the first sqlcon.close(); is because if I dont write it it will say connection is not closed which doesnt make sense to me because i have written a sqlcon.close(); down there...
