title: Refresh DataSource after SaveChange does not work
body: <p>I add data in an <code>ObjectSet</code> and did <code>SaveChanges</code> on <code>ObjectContext</code>. But the new data does not shown in the <code>DataGrid</code>!</p>
  
  <p><strong>Code:</strong>
  <code>
  <pre>
  bsWork.DataSource = Program.EC.Addresses;
  ...
  Address newAdr = new Address();
  //change properties newAdr
  ...
  Program.EC.Addresses.AddObject(newAdr);
  Program.EC.SaveChanges(SaveOptions.AcceptAllChangesAfterSave);</pre></code>

  bsWork.Add(newAdr);
  Program.EC.SaveChanges(SaveOptions.AcceptAllChangesAfterSave);
  ...
