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.
