Form Controls Assignment

I wish to create the below form and submit details to other form.

        private void Registration_Load(object sender, EventArgs e)
        {
            //Code present in this section will be executed when the form loads
            dtDOB.MaxDate = DateTime.Today;
        }

        private void btnSubmit_Click(object sender, EventArgs e)
        {

            ShowDetails D = new ShowDetails();
            D.data = txtName.Text + " Has Registerd for " + cbCourse.Text + " in College " + lbCollege.Text + "  Succesfully ";
            if (cbGraduate.Checked == false)
                D.data = D.data + " As you are not a Graduate student, and as per records of your date of birth " + dtDOB.Value.Date.ToString() + " you are eligible ";
                    this.Hide();
                    if (rbFemale.Checked == true)
                        D.data = D.data + "You are first Female Student";
                    D.data = D.data + rbComments.Text;
            D.Show();
        }
