Parameters

Name	Type	Description
columnIndex	Int32	A zero-based integer which identifies the visible index of the column.
rowIndex	Int32	A zero-based integer which identifies the absolute index of the row. To obtain the absolute row index by its index within the current page, use the ASPxPivotGrid.GetAbsoluteRowIndex method.
maxRowCount	Int32	An integer value that specifies the maximum number of data rows to be returned. -1 to retrieve all rows.
customColumns	List<String>	A list of columns in a data source, to be returned.

Returns

Type	Description
PivotDrillDownDataSource	A PivotDrillDownDataSource object that contains the underlying data.

Remarks

To obtain the name of a column in a data source to which a pivot field corresponds, use the field’s OLAPDrillDownColumnName property.

Note

For MS SQL Server Analysis Services 2000, the customColumns parameter is ignored. In this instance, the CreateOLAPDrillDownDataSource method returns the granularity attributes.

Note

A note for MS SQL Server Analysis Services 2005 and 2008. If the customColumns list is null or empty, the CreateOLAPDrillDownDataSource method returns the columns corresponding to the current column, row and data PivotGrid fields. In addition, it returns filter fields if a filter is applied to them. Otherwise, it returns the columns specified by the customColumns list.

Note

If a filter is applied to a field, then that filter is taken into account if the corresponding drill-down column was returned from the server by the CreateOLAPDrillDownDataSource method.

Note

The CreateOLAPDrillDownDataSource method is not supported for cells corresponding to calculated measures.

Note

If multiple filter items are selected in a Filter Field, the drill-down data source cannot be created due to an MS SQL Server Analysis Services limitation. In this instance, the CreateOLAPDrillDownDataSource method throws an exception.
