Returns an OLAP member for the specified field value.

Namespace: DevExpress.XtraPivotGrid

Assembly: DevExpress.XtraPivotGrid.v22.2.dll

NuGet Package: DevExpress.Win.PivotGrid


public IOLAPMember GetFieldValueOLAPMember(
    PivotGridField field,
    int lastLevelIndex


Name Type Description
field PivotGridField

A PivotGridField object that represents the Pivot Grid Control field.

lastLevelIndex Int32

An integer value that specifies the cell’s index.


Type Description

An object that implements the IOLAPMember interface. null (Nothing) if the specified summary cell doesn’t correspond to the specified field’s value.


If the field parameter specifies the row field, the lastLevelIndex parameter specifies the summary cell’s vertical position (within a column). If the field parameter specifies the column field, the lastLevelIndex parameter specifies the summary cell’s horizontal position (within a row).



The following example demonstrates how to implement sorting by summary in OLAP mode. In this example, values of the Fiscal Year field are sorted by the Australia | Bendigo column summary values.

Sorting by summary in OLAP

Two PivotGridFieldSortCondition objects contain OLAP members that correspond to Australia and Bendigo values. The PivotGridControl.GetFieldValueOLAPMember method obtains these values. Obtained values specify columns by which the Fiscal Year field should be sorted and are stored in the Fiscal Year’s PivotGridFieldSortBySummaryInfo.Conditions collection. OLAP members can be obtained only for visible field values. For this reason, the Australia field value is expanded before initializing OLAP members to obtain the Bendigo member. The PivotGridFieldSortBySummaryInfo.Field property specifies the data field whose summary values should be used to sort values of the Fiscal Year field.

This sample uses the Adventure Works 2008 cube.

            finally {
                // Unlocks the pivot grid and applies changes.
