TcxPivotGridCustomDataSet Class
Represents the base class for all classes that cache pivot grid data into an in-memory read-only dataset to be visualized in data-aware controls.
Declaration
TcxPivotGridCustomDataSet = class(
TdxCustomMemData,
IcxPivotGridListener
)Remarks
This class uses pivot grid data to create an in-memory read-only dataset and update it in response to changes to the pivot grid’s summary data, field layout, or selection. With a TDataSource component, this dataset can be bound to any data-aware control.
In addition to the members inherited from the base TdxCustomMemData class, the TcxPivotGridCustomDataSet class introduces members that allow you to:
Link to the pivot grid (PivotGrid).
Create a dataset and synchronize its structure and contents with a linked pivot grid (the CreateData method and the SynchronizeData property).
Track changes to the dataset’s structure and contents (OnDataChanged).
Perform specific actions after a dataset’s field has been created (OnCreateField).
TcxPivotGridCustomDataSet descendants – the TcxCustomPivotGridSummaryDataSet and TcxCustomPivotGridDrillDownDataSet classes – represent datasets that cache summary data and drill-down data of cross cells, respectively.
