TDataSourceLink.RecordChanged Method
|
RAD Studio VCL Reference
|
|
|
Informs the TDBLookupControl of changes in the current record or field of the DataSource.
procedure RecordChanged(Field: TField); override;
virtual __fastcall RecordChanged(TField Field);
Applications cannot call RecordChanged directly. It is triggered automatically after changes in the contents of the current record. If the Field parameter is the key field of the lookup control, or if the Field parameter is nil (Delphi) or NULL (C++), indicating that the entire record changed, RecordChanged causes the lookup control to refetch the value of its key field.
