private Rectangle rect=new Rectangle(20, 20, 300, 200);
private Pen rectPen=Pens.Black;

public Form1() {
    InitializeComponents();
    panel=new Panel();
    panel.Bounds=new Rectangle(…);
    panel.Paint+=panelPaintHandler;
    Controls.Add(panel);
}

protected void panelPaintHandler(object sender, PaintEventArgs e) {
    Graphics g=e.Graphics;
    if (paintRectFlag) g.DrawRectangle(rectPen, rect);
}

protected void buttonClickHandler(object sender, EventArgs e) {
    paintRectFlag=!paintRectFlag;   // toggle visible flag
    panel.Invalidate();
