title: Force resize of GridView columns inside ListView
body: <p>I have a <code>ListView</code> WPF control with a <code>GridView</code>.  I'd like to resize the <code>GridView</code> columns when the content of the columns changes.</p>
  
  <p>I have several distinct data sets but when I change from one to another, the size of each columns fits the previous data. I'd like to update dynamically. How can I do that?</p>
