title: Postback parent page when using an ASP.NET ModalPopup control
body: <p>I have a custom UserControl that displays a modal popup (from the Ajax Toolkit).  The control allows the user to add a note to a customer record which the parent page displays in a GridView.</p>
  
  <p>I'm unable to force the parent page to reload the grid after the user clicks the "Add Note" button on the modal popup and closes it.  The note is added to the database correctly, but I have to manually refresh the page to get it to display instead of it automatically refreshing when I save+close the popup.</p>
