예제

다음 예제에서는 사용 하는 방법에 설명 합니다 GridViewEditEventArgs 개체 성 백서를 사용 하 여 작성자가 포함 된 행을 편집 하려면 사용자가 편집 작업을 취소 하는 이벤트 처리 메서드에 전달 합니다.The following example demonstrates how to use the GridViewEditEventArgs object passed to the event-handling method to cancel the editing operation if the user attempts to edit a row that contains an author with the last name White.

설명

GridView 를 발생 시킵니다를 RowEditing 있는 편집 단추 이벤트 (단추를 사용 하 여 해당 CommandName 속성이 "Edit"로 설정)를 클릭 하기 전에 GridView 컨트롤이 편집 모드로 전환 합니다.The GridView control raises the RowEditing event when an Edit button (a button with its CommandName property set to "Edit") is clicked, but before the GridView control enters edit mode. 이 옵션을 사용 하면이 이벤트가 발생할 때마다 편집 작업을 취소 하는 등 사용자 지정 루틴을 수행 하는 이벤트 처리 메서드를 제공할 수 있습니다.This allows you to provide an event-handling method that performs a custom routine, such as canceling the edit operation, whenever this event occurs.

GridViewEditEventArgs 개체 편집 되는 행의 인덱스를 확인 하 고 편집 작업을 취소 해야 함을 나타낼 수는 이벤트 처리 메서드에 전달 됩니다.A GridViewEditEventArgs object is passed to the event-handling method, which allows you to determine the index of the row being edited and to indicate that the edit operation should be canceled. 편집 작업을 취소 하려면 합니다 Cancel 의 속성을 GridViewEditEventArgs 개체를 true입니다.To cancel the edit operation, set the Cancel property of the GridViewEditEventArgs object to true.

이벤트를 처리 하는 방법에 대 한 자세한 내용은 참조 하세요. 이벤트 처리 및 발생합니다.For more information about how to handle events, see Handling and Raising Events.
