title: silverlight domain datasource refreshed only after F5
body: <p>I am using SL4 with WCF RIA services. I have a domain datasource which I am using to populate a listbox.
  I have attached a context menu attached to the list items that I want to trigger an update to a fields value in the database.
  so I am trying</p>
  
  <pre><code>EmployeeDetail employee = (EmployeeDetail)sender;
  if(employee.EmployeeDetails!=null)
  employee.formEmployee.CommitEdit();
  dsEmployee.SubmitChanges();
  </code></pre>
  
  <p>So the code works ok I see the update in the database, however the listbox hasn't been refreshed. If I press F5 then I see the change in the silverlight application however what do I need to do to refresh the lists datasource?</p>
