title: Add a 'placeholder' row in a GridView
body: <p>I want to allow users to go through a set of tables, first creating a row in one table, then creating a row that is inserted with the previous row as a key.</p>
  
  <p>Because the subsequent GridViews have no data until their previous rows are entered, the HTML for the table isn't rendered.</p>
  
  <p>I want to add a placeholder row to ensure that the GridViews are always present with just an example row saying something like 'No data added yet'.</p>
  
  <p>Is this possible? Perhaps a dummy row added programatically rather than being a feature of the control?</p>
  
  <p>Thanks.</p>
