Sort Order on Group Headers

[Eric]

I have a ScheduleView control on a page that I have multiple groupings and filtering. Throughout the application, I am sorting my Resources on DisplayName. The problem is that I want my group headers sorted by the DisplayName property, but the ScheduleView control is ignoring the sort that I am applying in my SQL query, from my domain service, when populating the collection on the view model, when retrieving the collection from the view model and when setting the source for the grouping. How can I get the Group Heading to sort my resources on a property I specify?

Thanks,
EZ
