Remarks
PivotGridControl prevents an OLAP server from processing empty tuples (tuples for which there is no data in a particular measure) by default. This allows the pivot grid to deliver better performance.
To exclude empty tuples from the complete set, PivotGridControl uses the NonEmpty MDX function. The control uses this function to calculate Top N or when you expand the PivotGridControl’s values.
You can use the PivotGridOptionsOLAP.ShowColumnsWithNoData or PivotGridOptionsOLAP.ShowRowsWithNoData properties to show items with no data on columns or rows.
In some instances, the NonEmpty function causes valuable data to be filtered out. This may happen when NonEmpty is used with a calculated measure.
If you find any values missing from the pivot grid while using calculated measures, try setting the OLAPUseNonEmpty property to false for these measures. Note that this may slow the performance.
Note
The OLAPUseNonEmpty property is in effect only for fields that define measures.
