title: MasterPage using Masterpages, and inheritance
body: <p>I've got a "Master" Masterpage, and I've got 2 "Sub" Masterpages.  Those 2 subs have their masterpage property set to the "Master" Masterpage.  All good so far.</p>
  
  <p>Well, I was told today to also make Sub1 and Sub2 actually "inherit" from the Master Masterpage.  I thought they were being imprecise with their language, but no, she wanted me to change the Class definition to </p>
  
  <pre><code>public partial class Sub2 : TheMaster 
  </code></pre>
  
  <p>(those aren't the names).</p>
  
  <p>So, now I've got Sub1 and Sub2 that are master pages, and have a master page of TheMaster, and ALSO they are of the class of "TheMaster"</p>
  
  <p>I'm quite confused by this, and not sure what kinds of effects this will have.  It seems to compile and run fine right now, but we are just starting this 6 month project today, and I don't want to get to month 5 and find out that we have a major design flaw.</p>
  
  <p>Can anyone tell me that this is totally fine, or that we are completely messed up?</p>
  
  <p>I'm scared...hold me.</p>
  
  <p>EDIT:  Clarification -- the reason she wanted me to also inherit from the master master page is that we set some things in that page, and we want them available to the sub master pages.  Things like the current node in the sitemap that the rendered page is, some user account stuff, and much more.</p>
