I have a RadGrid configured with Paging and Grouping with Aggregates
- AllowPaging = true
- ShowGroupFooter = true
I have 1 column defined as Aggregate
The RadGrid, by default, appears to Aggregate for items in the current page (i.e. The Grouping Total that appears in the GroupFooter... only applies to visible items on the currently selected page (even when the group extends into other pages).
How can I implement a custom aggregate in which I sum all of the values for a particular column within a group (across all data items that are in the group / i.e. across all pages)?
