Answer 1

This should solve your problem:

private void get_value_Click(object sender, EventArgs e)
{
  for (var c in flowLayoutPanel1.Controls)
  {
    var t = c as TextBox;
    if (t != null)
    {
      richTextBox1.SelectedText  = "\r\n" + t.Text;
    }
  } 
}

Answer 2

In your method get_value_Click you aren't using any of the text boxes that were added to the flow layout panel. Something similar to Wolfgang Ziegler's answer should work but you will need to check the Type and Name in case you have other controls in the flow layout panel.

Answer 3

private void get_value_Click(object sender, EventArgs e)
    {
        for (i = 1; i <= 3; i++)
        {
            string value = this.flowLayoutPanel1.Controls["Text Box" + i].Text;
            richTextBox1.SelectedText  = "\r\n" + value;
        }
    }

This ought to do it.
