title: Change Foreground item of ListView
body: <p>I want to change the <code>Foreground</code> of a item on a <code>ListView</code> of my UWP.
  I am using:</p>
  
  <pre><code>int i_DeleteRow = ListView1.SelectedIndex;
  var item = ListView1.Items[i_DeleteRow] as ListViewItem;
  
  if (item != null)
  {
      item.Foreground = new SolidColorBrush(Colors.Red);
  }
  </code></pre>
  
  <p>But with this code <code>item</code> is always null.
  Any help is appreciated.</p>
