title: Web user control as masterpage with two child views
body: <p>I'm building custom .NET web user control for Umbraco, which looks like single page, with a sidebar  (which holds IDs of content items) on the left side of page, and two different content views(which have content by id displayed here) to the right of it.</p>
  
  <p>The thing is, i don't know if this is possible to do something like masterpage/childs principle(in terms of this web user control), so i'll have something like "Master page" with this sidebar, and will render one of two child views to the right of it, depending on id selected from sidebar?</p>
  
  <p>Or maybe there should be some workaround used here?
  Will be much appreciated on any help here(like information about how that can be done, what information shall i seek for etc.), as i'm completely new in this kind of stuff.</p>
