How to add Control over GraphicsPath

I haved drawn a round Rectangle using OnPaint event:

   protected override void OnPaint(PaintEventArgs e)
        {
            base.OnPaint(e);

            GraphicsPath path = RoundedRectangle.Create(5, 5, 20, 20);
            e.Graphics.DrawPath(Pens.Black, path);
        }

and i want to draw a control over that rectangle . e.g: a TextBox

Question: Is there a way to know the Location or the Point of GraphicsPath to set my control over it?
