sir try nyo po ito

di ko po sure dun sa ClassRegistrationQuery ay yung ClubRegistrationQuery.

private ClubRegistrationQuery clubRegistrationQuery;
        private int ID, Age, count;
        private string FirstName, MiddleName, LastName, Gender, Program;

        private void button3_Click(object sender, EventArgs e)
        {
            RefreshListofClubMembers();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            count = clubRegistrationQuery.dataTable.Rows.Count;
            clubRegistrationQuery.RegisterStudent(count, long.Parse(tbStudentID.Text), tbFirstName.Text, tbMiddleName.Text, tbLastName.Text, int.Parse(tbAge.Text), cbGender.Text, cbProgram.Text);
        }

        private long StudentId;
        private void frmClubRegistration_Load(object sender, EventArgs e)
        {
            clubRegistrationQuery = new ClubRegistrationQuery();
            RefreshListofClubMembers();
        }
        public void RefreshListofClubMembers()
        {
            clubRegistrationQuery.DisplayList();
            dataGridView1.DataSource = clubRegistrationQuery.bindingSource;
        }
