My message wont show on my textbox?
<p>I am trying to fill a form (Movie information such as Title, Year and Genre) and then show it in a textbox (enable=false).
I have 2 classes and a Form (with 2 textboxes (for user input), 2 buttons, 1 to register the movie infos, and 1 to show the infos in a 3rd textbox (the one that is Disabled).</p>

<pre><code>class Movies
    {
        public string Title { get; set; }
        public int Year { get; set; }

        public string ReturnMovie()
        {
            return Title + " (" + Year.ToString() + ")";
        }
    }

class Genres
    {
        public string Genre { get; set; }

        public string ReturnGenre()
        {
            return Genre;
        }
    }
</code></pre>

<p><strong>MainForm:</strong></p>

<pre><code>        bool btnRegisterClicked = false;

        Movies m1 = new Movies();
        Genres g1 = new Genres();

        private void btnRegister_Click(object sender, EventArgs e)
        {
            btnRegisterClicked = true;

            if (btnRegisterClicked == true)
            {
                if (txtTitle.Text.Length == 0)
                {
                    MessageBox.Show("Enter a title for the movie.");

                    btnRegisterClicked = false;
                }

                else if (txtYear.Text.Length &lt; 4)
                {
                    MessageBox.Show("Enter a valid year.");

                    btnRegisterClicked = false;
                }

                else if (chkGenre.SelectedIndex == -1)
                {
                    MessageBox.Show("Select the genre(s) of the movie.");

                    btnRegisterClicked = false;
                }

                else
                {
                    txtTitle.Text = m1.Title;
                    txtYear.Text = m1.Year.ToString();
                    chkGenre.Text = g1.Genre;
                }

                txtTitle.Clear();
                txtYear.Clear();
                chkGenre.ClearSelected();
            }
        }

        private void btnShow_Click(object sender, EventArgs e)
        {
            txtShow.Text = m1.ReturnMovie() + g1.ReturnGenre();
        }
    }
</code></pre>
