Sorting Group Rows by Summary Values

  • 2 minutes to read

When the grid’s data is grouped, rows are always sorted against the grouping columns. By default, group rows are sorted in the order specified by the corresponding grouping column. If the grid displays group summaries, group rows can also be sorted by their summary values.


To sort group rows by their summary values in code:

Remove the GridGroupSummarySortInfo object from the GroupSummarySortInfo collection to clear the summary sorting.

Users can sort group rows by summary values through a column header’s context menu.

Refer to the following help topic for more information: Sorting Group Rows by Summary.


This example demonstrates how to sort group rows by summary values in code:
