title: Disallow button press feedback in non-sortable WPF ListView header
body: <p>For a WPF ListView bound to an simple list that has no need or support for sorting, how you do make it so that the user doesn't get button press feedback when he clicks on a header? By default, clicking the middle of a column header feels like a button press for which nothing happens.</p>
  
  <p>An example of the look and feel I'm trying to achieve is in System Control Panel > Advanced system settings > User Profile Settings. The Profile list does not support sorting. Accordingly, the header does not respond when clicked (except for column resize clicks).</p>
