title: what's the proper way to tell if new rows were added to a DataTable after the DataAdapter's Fill() method is called?
body: <p>I've been playing with the DataTable's RowChanged and RowChanging events, also with the TableNewRow event, and can't get this to work.</p>
  
  <p>essentially what I have is an event handler procedure with code that fills a DataTable and then another event handler procedure with code that refills the same DataTable, and should notify the user that, between calls to the Fill method, new rows were added to the Table (assuming that that is the case).</p>
  
  <p>I've also been playing with the DataRow's indexer and specifying the DataRowVersion and can't get this to work.</p>
  
  <p>I've been playing with the DataAdapter's FillLoadOption method and still can't get this to work.</p>
  
  <p>Can someone give me a hint?</p>
