title: WPF Miller Columns
body: <p>I'm having a hard time implementing a <a href="http://en.wikipedia.org/wiki/Miller_columns" rel="nofollow">Miller Column</a> interface in WPF, and was wondering if anyone has seen an implementation I could borrow from.  I've done some searching and can't find anything myself.</p>
  
  <p>Currently I have my data organized in a hierarchy so that it can be placed in a TreeView, but I'd like to add the Miller Column view as an option in my program.</p>
