예제

다음 코드 예제에서는 및 메서드를 모두 보여 줍니다 CancelCurrentEdit EndCurrentEdit .The following code example demonstrates both the CancelCurrentEdit and the EndCurrentEdit methods. 메서드를 호출 하면 CancelCurrentEdit 데이터에 대 한 변경 내용이 삭제 됩니다.When you call the CancelCurrentEdit methods, changes made to the data are discarded. 메서드를 호출 하면 EndCurrentEdit 변경 내용이 유지 됩니다.When you call the EndCurrentEdit method, the changes are kept.

설명

이 메서드는 데이터 소스에서 인터페이스를 구현 하는 경우에만 지원 됩니다 IEditableObject .This method is supported only if the data source implements the IEditableObject interface. 이 경우 변경 내용이 저장 됩니다.In that case, changes will be saved. 개체가 인터페이스를 구현 하지 않는 경우 IEditableObject 에는 데이터에 대 한 변경 내용이 저장 되지 않습니다.If the object does not implement the IEditableObject interface, changes made to the data will not be saved.
