title: Sitecore MVC form postback does not return a full layout
body: <p>i'm using Sitecore 7 with MVC enabled. I have a cshtml layout that has a header, menu, footer and placeholder in it.</p>
  
  <p>When i submit a form in the page with POST method, it gets to the controller and the controller is returning a viewresult for some reason only that particular html from the viewresult gets rendered to the page. Meaning that after doing a postback the header, menu, footer is gone and only the html from the result gets rendered on the page.</p>
  
  <p>Is this behaviour expected or am i doing something wrong? i would expect that when i do form postback it would return the viewresult with the layout rendered as well</p>
