Can someone point me to an example of using the GroupFooterTemplate with the MVC Server Wrappers?
From what I can tell, this should work when I 'group by' any column:
.GroupFooterTemplate( f =>
+ f.Sum )
Is there any other setup / configuration that's needed to make it work?
I've add this to the DataSource as well without success
.Aggregates( a => a.Add(c => c.Quantity).Sum())
