Remarks
Important
The customColumns parameter is in effect in Server and OLAP modes only; otherwise, it is ignored.
The CreateDrillDownDataSource method allows you to retrieve the subset of records from the PivotGrid’s underlying datasource associated with the specified cell.
Important
Do not call the CreateDrillDownDataSource method in the PivotGridSettings.CustomSummary and PivotGridSettings.CustomUnboundFieldData event handlers to avoid a stack overflow exception. Instead, handle the PivotGridSettings.CustomCellValue event and call the CreateDrillDownDataSource method in the event handler.
