The ASP.NET Core Data Grid relies on the data manager to aggregate column values. Default aggregate types such as sum, max, min, average, and count can be used. Formatted aggregate values are displayed in aggregate-enabled columns.
The ASP.NET Core Data Grid allows users to define custom aggregate logic for a particular aggregate column. This requires a custom aggregate function that holds custom logic to calculate aggregate value of the Data Grid columns.
On each cell save of the batch editing (cell editing), Data Grid refreshes aggregate values with the edited value of the cell. These aggregated values are volatile.
