Group Summary
The GridControl supports group summaries so your end-users can easily manage and analyze information in the grid. A group summary is an aggregate function value calculated across all data rows within a group.
In this demo, the grid data is grouped by the Date column. A group summary is computed for the Total column using the Sum function. The summary values are automatically displayed in individual group rows.
You can select another aggregate function to compute a summary or delete it using the context menu invoked when you touch and hold any group row.
