TcxCustomPivotGridSummaryDataSet Class

Represents the base class for all classes that cache a pivot grid’s summary data into an in-memory read-only dataset.

Declaration

delphi

TcxCustomPivotGridSummaryDataSet = class(
    TcxPivotGridCustomDataSet
)

Remarks

This class doesn’t introduce any new members, but instead implements the following:

Creates a dataset field for each row, column, and data field. This table is populated with cross cell summary values corresponding to source pivot grid fields as shown in the image below.

For reference purposes, stores a value corresponding to a source field’s area to a dataset field’s Tag property. This value can be useful when you need to determine a source field’s area using a dataset’s field.
Enables the dataset’s synchronization only in response to changes to a pivot grid’s summary data or field layout.
Creates the RecID auto increment dataset field, to store identity values for dataset records.

The TcxPivotGridSummaryDataSet class (a TcxCustomPivotGridSummaryDataSet descendant) represents a component that can be used in your projects to provide a pivot grid’s summary data for data-aware controls.
