Reloads data from all underlying data sources on demand and updates dashboard content.
procedure ReloadData; virtual;
Dashboard items (grids, maps, charts, etc.) defined in the dashboard layout can use multiple data sources bound using data connection components.
Data connection components automatically reload and re-serialize data from underlying data sources every time the TdxDashboardControl/TdxReport component starts to import data for design, preview, and export operations. If data changes within an underlying data source/database between these operations, dashboard content is not updated automatically.
To update cached data from underlying data sources and refresh dashboard content on demand, call the ReloadData procedure.
A ReloadData procedure call refreshes serialized data accessible through the ConnectionString property for all TdxBackendDataSetJSONConnection components with enabled Active and AutoRefreshData properties.
