Aggregates (Vue)

The MultiRow control supports CollectionView-based grouping just like FlexGrid.

When showing grouped data, the control adds group header rows that can be used to collapse and expand the groups and also to display aggregate statistics for the groups.

To ensure aggregates are visible on the group header rows, set the multiRowGroupHeaders property to true.
