title: How might I remove focus from all items in a ListView control?
body: <p>In a <code>ListView</code> control, the focus is on some <code>Item</code> within that control - that is, the control maintains its own internal notion of what is in focus, which can be retrieved using the <code>FocusedItem</code> property. </p>
  
  <p>I would like <em>no</em> items to be focused. In other words, I want the <code>FocusedItem</code> property to set to <code>null</code>. Any idea how I might accomplish this?</p>
