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. Aggregate values can be formatted before being displayed in a cell.
Custom aggregate logic can be provided for a column. This requires a custom aggregate function that holds custom logic to calculate aggregate value.
On each cell save of batch editing (cell editing), Data Grid refreshes the aggregate values with edited value of the cell. These aggregated values are volatile.
