Called whenever data changes in the current record
Source position: db.pas line 1931
published property TDataSource.OnDataChange : TDataChangeEvent |
OnDatachange is called whenever a field value changes: if the Field parameter is set, a single field value changed. If the Field parameter is Nil, then the whole record changed: when the dataset is opened, when the user scrolls to a new record. This event handler can be set to react to data changes: to update the contents of non-DB-aware controls for instance. The event is not called when the datasource is not enabled.
