I haven't done a lot of WPF lately, so I'm not sure if this is what you're looking for, but check out this article: Customizing “lookful” WPF controls – Take 2. It's a bit complex, but it seems to address the same question you're asking. UPDATE: The website seems gone, but you can find the article in the archive. SEE Scott Chamberlain's ANSWER WITH THE SAMPLE CODE (thanks Scott).
