title: What is ItemsControl.GetContainerForItemOverride used for?
body: <p>While looking for a solution for an issue I am having, I ran into <code>GetContainerForItemOverride()</code> and I don't think I understand the <a href="http://msdn.microsoft.com/en-us/library/system.windows.controls.itemscontrol.getcontainerforitemoverride.aspx" rel="noreferrer">documentation</a>. </p>
  
  <p>MSDN says: </p>
  
  <blockquote>
    <p>Creates or identifies the element that is used to display the given
    item.</p>
  </blockquote>
  
  <p>However, there's no given item - there's no parameter being passed into the method.</p>
  
  <p>Out of curiosity - what's the purpose of this method?</p>
  
  <p>(I obviously searched for it and could not really find an answer)</p>
