TDataSet.OnDeleteError property

Declaration

property OnDeleteError: TDataSetErrorEvent read FOnDeleteError write FOnDeleteError;

Description

OnDeleteError is triggered when the Delete method fails to delete the record in the underlying database. The event handler can be used to indicate what the response to the failed delete should be. To this end, it gets the exception object passed to it (parameter E), and it can examine this object to return an appropriate action in the DataAction parameter. The following responses are supported:

daFail

The operation should fail (an exception will be raised).

daAbort

The operation should be aborted (edits are undone, and an EAbort exception is raised).

daRetry

Retry the operation.
