TDataSet.BeforeDelete

Event triggered before a Delete operation.

Declaration

Source position: db.pas line 1753

public property TDataSet.BeforeDelete : TDataSetNotifyEvent
  read FBeforeDelete
  write FBeforeDelete;

Description

BeforeDelete is triggered at the start of the TDataset.Delete operation, when the dataset is still in dsBrowse state. The event handler can be used to abort the delete operation: if an exception is raised during the event handler, then the delete operation stops. The event is followed by a TDataset.BeforeScroll event. If the dataset was in insert mode when the Delete method was called, then the event will not be called, as TDataset.Cancel is called instead.
