1) You just set the controls to be visible, for example textBox2.Visible = true; 2) Not sure what you are asking, could you explain more?

please explain your question. I don't understand what u want to say?

private void button1_Click(object sender, EventArgs e)
        textBox1.Visible = false;

private void button2_Click(object sender, EventArgs e)
        textBox1.Visible = true;
