Event triggered when a new record is created.

Declaration

Source position: db.pas line 1763

public property TDataSet.OnNewRecord : TDataSetNotifyEvent
  read FOnNewRecord
  write FOnNewRecord;

Description

OnNewRecord is triggered by the TDataset.Append or TDataset.Insert methods when the buffer for the new record's data has been allocated. This event can be used to set default value for some of the fields in the dataset. If an exception is raised during this event handler, the operation is cancelled and the dataset is put again in browse mode (TDataset.State is again dsBrowse).
