title: Silverlight DataGrid Updating SelectedItem from code
body: <p>When I update a datagrid SelectedItem from code (via a bound object in a ViewModel), how to I get the visual grid to highlight the newly selected item?</p>
  
  <p>Thanks,<br>
  Mark</p>
  
  <p><strong>UPDATE:</strong> This is still an issue for me. My SelectedItem property already implements change notification, but the datagrid is not <em>VISUALLY</em> displaying which row has been selected - i.e. it is not getting highlighted.</p>
