title: Display different messages in grid view for not having bound data and no results retrieved
body: <p>I have a ASP.NET <code>GridView</code> which I want to populate with a message "No results found" when there are no results to be displayed. Initially I do not want to bind data and have the grid view display "You still need to search". </p>
  
  <p>Using an <code>EmptyDataTemplate</code> and just binding <code>null</code> to the grid view only displays one type of message. Is there a way to accomplish that the initial message is as above and a different message is displayed when searched and no results are bound to the <code>GridView</code>?</p>
  
  <p>Thanks.</p>
