Remarks
You can use a column’s GridColumn.SummaryItem property to define an aggregate function to be calculated by column values and to format its resulting value. The formatted value will be displayed within the column’s corresponding view footer cell.
By default, the AutoUpdateTotalSummary property is set to true. If there is a summary item calculated against a specific column and a cell value in this column is changed, the grid automatically updates the summary in the following cases:
- On moving focus to another row.
- On pressing the End Edit button in the Data Navigator.
However, you may want to disable this behavior. For example, disabling automatic summary value recalculation results in performance benefits when working with large data arrays. In this case, you need to update the total summary manually, when required, via the GridView.UpdateTotalSummary method.
