OLAP Server Note
MS SQL Server Analysis Services 2000 The customColumns parameter is ignored and the CreateDrillDownDataSource method returns the granularity attributes.
MS SQL Server Analysis Services 2005 and 2008 If the customColumns list is null or empty, the CreateDrillDownDataSource method returns the columns related to the current column, row and data PivotGrid fields. The method also returns filter fields, if any.
Any OLAP Server If returned records contain a column used as a filter in Pivot Grid, the returned data are filtered.

IMPORTANT

Do not call the CreateDrillDownDataSource method in the PivotGridControl.CustomSummary and PivotGridControl.CustomUnboundFieldData event handlers to avoid a stack overflow exception. Use the event arguments' methods instead - the PivotGridCustomSummaryEventArgsBase<T>.CreateDrillDownDataSource and CustomFieldDataEventArgsBase<T>.GetListSourceColumnValue methods, respectively).

In OLAP mode, this method equals to the PivotGridControl.CreateOLAPDrillDownDataSource method with the customColumns parameter set to null.
