There are a lot of different ways to scroll things.  The best way depends on
your requirements.

You can put any control into a fixed size area by putting it in a scrollable
div such as this:

<div id="Layer1" style="position:relative;width:350px;height:200px;overflow:
scroll;">control goes here</div>

The key is to use the "overflow" CSS attribute.Here's more info:

Another option is to put your control in an IFrame.

There are also other more complex techniques with richer client side
functionality such as XML data islands and AJAX.
