Drawing text on a panel that scrolls

Question

I am drawing various rectangles with texts inside them.  Right now the method draws to the main form(and it doesn't scroll even with setting autoscroll to true).  What I would like to do is to draw on a panel and make this panel scrollable.  Here is the drawing routine that someone else helped me with.  I would like to use this routine to draw the text and rectangle because it does EXACTLY what i need.  What I need is how to draw this text on a panel and make that panel scroll if appropriate.  Thank you in advance.
