                                  As this question seems to be more related to the Spreadsheet control engine so I've created a separate ticket on your behalf (T831547: How to track changes in ASP.NET Spreadsheet control) and passed it to our Spreadsheet team. It has been placed in our processing queue, please await our answer.
                                  As far as XAF is concerned, you can access the spreadsheet control within an XAF view as described at How to: Access the Spreadsheet Control.  Let me know if you experience any further difficulties with the XAF integration.
