title: How to save persistent objects databound to a DataLayoutControl (DevExpress tools)?
body: <p>I have a small form displaying the DataLayoutControl component. </p>
  
  <p>If I use a GridControl the objects get saved. If I use the DataLayoutControl (which shows them individually) they do not get saved after they are changed. The underlying object is changed after the user interface edits, but doesn't get saved. </p>
  
  <p>How can I enable this ?</p>
  
  <p>PS: I have tried UnitOfWork.CommitChanges (i have one uow going through the whole architecture) to no avail. </p>
