C# Adding button with value at runtime [closed]

Answer 1

I propose such decision

Main form:

namespace stackoverflow
{
    public partial class MainForm : Form
    {
        private static Form2 new_form = new Form2();

        public MainForm()
        {    
            InitializeComponent();
            new_form.Show();
        }


        void Button1Click(object sender, EventArgs e)
        {
            new_form.CreateBtn( richTextBox1.Text );
        }
    }
}

Second form:

namespace stackoverflow
{
    public partial class Form2 : Form
    {
        private Button btn = null;

        public Form2()
        {
            InitializeComponent();
        }

        public void CreateBtn( string text ) {
            if ( btn == null ) {
                btn= new Button();
                btn.Parent = this.tabPage1;
            }
            btn.Text = text;
            this.Refresh();
        }
    }
}
