need PropertyGrid with drill-down, similar to QuickWatch
<p>I am trying to display object data members in a generic way.  I started by using PropertyGrid, which satisfies my needs as far as simple properties are concerned.  However, it doesn't let the user drill-down into data members.  It allows browsing into collections, but the interface is a bit awkward.</p>

<p>I'm basically looking for something with the features of QuickWatch.  Does anybody know of any libraries that can do drill-down?</p>
