예제

다음 코드 예제를 사용 하는 방법에 설명 합니다 DetailsViewDeletedEventArgs 에 대 한 이벤트 처리기에 전달 된 개체를 ItemDeleted 삭제 작업 중에 예외가 발생 했는지 여부를 결정 하는 이벤트입니다.The following code example demonstrates how to use the DetailsViewDeletedEventArgs object passed to the event handler for the ItemDeleted event to determine whether an exception occurred during a delete operation.

설명

DetailsView 를 발생 시킵니다를 ItemDeleted 이벤트 있는 삭제 단추 (단추를 사용 하 여 해당 CommandName 속성이 "Delete"로 설정) 컨트롤 내에서 클릭 한 후는 DetailsView 레코드를 삭제 합니다.The DetailsView control raises the ItemDeleted event when a Delete button (a button with its CommandName property set to "Delete") within the control is clicked, but after the DetailsView control deletes the record. 이 옵션을 사용 하면이 이벤트가 발생할 때마다 삭제 작업의 결과 확인 하는 등 사용자 지정 루틴을 수행 하는 이벤트 처리기를 제공할 수 있습니다.This allows you to provide an event handler that performs a custom routine, such as checking the results of a delete operation, whenever this event occurs.

DetailsViewDeletedEventArgs 개체가 영향을 받는 레코드와 발생 한 예외의 수를 확인할 수 있는 이벤트 처리기에 전달 됩니다.A DetailsViewDeletedEventArgs object is passed to the event handler, which allows you to determine the number of records affected and any exceptions that might have occurred. 삭제 작업의 영향을 받는 레코드 수를 확인 하려면 사용 된 AffectedRows 속성입니다.To determine the number of records affected by the delete operation, use the AffectedRows property. 사용 된 Exception 예외도 발생 했는지 여부를 결정 하는 속성입니다.Use the Exception property to determine whether any exceptions occurred. 예외가 처리 되었는지 여부를 이벤트 처리기를 설정 하 여를 나타낼 수도 있습니다는 ExceptionHandled 속성입니다.You can also indicate whether the exception was handled in the event handler by setting the ExceptionHandled property. 키 필드 및 삭제 된 레코드의 키가 아닌 필드 이름/값 쌍에 액세스 하려는 경우 사용 합니다 KeysValues 속성을 각각.If you want to access the name/value pairs of the key fields and non-key fields of the deleted record, use the Keys and Values properties, respectively.
