TcxPivotGridOLAPDataSource Class

A data source providing OLAP cube data for unbound ExpressPivotGrid controls.

Declaration

TcxPivotGridOLAPDataSource = class(
    TcxPivotGridCustomOLAPDataSource
)

Remarks

This class reads a linked OLAP cube’s metadata, interprets it in terms of pivot grid elements and provides data for the pivot grid control. To access OLAP cubes, the TcxPivotGridOLAPDataSource component uses a specially designed provider (a TcxCustomPivotGridOLAPProvider descendant), which maintains a connection. Link this component to an unbound pivot grid using the pivot grid’s OLAPDataSource property to visualize OLAP cube data.

In addition to the settings inherited from the base TcxPivotGridCustomOLAPDataSource class, the TcxPivotGridOLAPDataSource class introduces the properties that allow you to:

Select the provider to be used to access OLAP cube data (Provider, ProviderClass, or ProviderClassName).
Specify a cube name (Cube).
Activate or terminate the connection (Active).

Important
