title: Resize Datagrid Height after deselecting a RowDetailsTemplate
body: <p>I am using RowDetailsTemplate to display a nested datagrid for a row. Now the datagrid expands in height when I select a row to show this nested datagrid. But it doesn't reduce its height when the row is deselected.</p>
  
  <ol>
  <li><p>Is there a way to resize the datagrid to its original height after the row details have been collapsed?</p></li>
  <li><p>Is it possible to do it declaratively?</p></li>
  </ol>
