Remarks

In OLAP binding mode, when the control is bound to a cube on an OLAP server, the pivot grid does not calculate summaries itself. Instead, it delegates all data management and calculations to the server side. The raw data is not downloaded to the client side - only the results of calculations.

When an end-user clicks an expand button or the Expand All context menu item, the pivot grid queries the server for a list of child field values. If there are no child field values associated with the current field value, the field value cannot be expanded, and the FieldValueNotExpanded event is raised. This event can be handled, for example, to display a message that informs a user that the field value cannot be expanded.
