Generally speaking, the easiest way to size an element relative to the client screen is to give it a width specified as a percentage (e.g. 25%).  You can also size an object relative to the font size by specifying the width in terms of ems (e.g. 10em).
If percentages won't work, then the alternative is to use JavaScript to resize the object dynamically in the client's browser.  The downside to this is that JavaScript has to interact with the HTML elements that make up the control, rather than acting on the control directly.
