TDataSet.BeforeCancel property

Member of TDataSetpublicIn unit DB

Event triggered before a Cancel operation.

Declaration

pascal
property BeforeCancel: TDataSetNotifyEvent read FBeforeCancel write FBeforeCancel;

Description

BeforeCancel is triggered at the start of the Cancel operation, when the state is still one of the editing states ( dsEdit, dsInsert). The event handler can be used to abort the cancel operation: if an exception is raised during the event handler, then the cancel operation stops. If the dataset was not in one of the editing states when the Cancel method was called, then the event is not triggered.
