<p>I've created a Silverlight project that produces [something].xap file to package a few silverlight UserControls.  I would like to manipulate that .xap file through the use of javascript in the browser to show and hide user controls based upon java script events.</p>

<p>Is it possible to do this?</p>

<p>If so any sample could or links to documentation would be appreciated.</p>

<p>Thanks in advance</p>
