body: <p>How do I get a WPF DataGrid to save changes back to the database?  </p>
  
  <p>I've data-bound my DataGrid control to a DataTable object, and populated that table with a very simple SELECT query that retrieves some basic information. The data shows up just fine in the control.  </p>
  
  <p>But when I use the control to edit the data, the changes are not pushed back to the DB.  </p>
  
  <p>Does anyone know what I'm missing?</p>
