In 2007:

      Button btn = new Button();


        protected override void CreateChildControls()
        {
            btn.Text = "Set the Property";
            btn.Click += new EventHandler(btn_AddLink);
            this.Controls.Add(btn);
        }


        private void btn_AddLink(Object sender, EventArgs e)
        {
            btn.Text = "Changed Text";
        }
