Calendar Resources

New to this forum and new to calendar control so I hope I have posted this ok.

I have been adapting the calendar sample code supplied with the control and using the sqlhelper functions into an access database. I have got the code working and moving on to multi resources. I have the resources loading from the database and displaying events against all resources. The problem i have is that only the first resource updates when edited, all the others amend the underlying database but don't change on the control until the datasource is re-opened. I think it is to do with the changeevent on the dataproviders for each resource but I am stuck. When a change is made to the first resource it fires the populate events however all other resources just go through the prepopulate and not rereading the events. Thanks in advance for any help.
