TdxCustomReportControl.ReloadData Method

Reloads data from all underlying data sources on demand and updates report content.

Declaration

procedure ReloadData; virtual;

Remarks

Data connection components automatically reload and re-serialize data from underlying data sources every time the TdxReportControl/TdxReport component starts to import data for design, preview, and export operations. If data changes within an underlying data source/database between these operations, report placeholders are not updated automatically.

To update cached data from underlying data sources and refresh report placeholders on demand, call the ReloadData procedure.

ReloadData and VCL-Compatible Datasets

A ReloadData procedure call refreshes serialized data accessible through the ConnectionString property for all TdxBackendDataSetJSONConnection components with Active and AutoRefreshData properties enabled.
