FormViewInsertedEventArgs.KeepInInsertMode 속성
정의
중요
일부 정보는 릴리스되기 전에 상당 부분 수정될 수 있는 시험판 제품과 관련이 있습니다. Microsoft는 여기에 제공된 정보에 대해 어떠한 명시적이거나 묵시적인 보증도 하지 않습니다.
삽입 작업 후에 FormView 컨트롤의 삽입 모드를 유지할지 여부를 나타내는 값을 가져오거나 설정합니다.
public:
property bool KeepInInsertMode { bool get(); void set(bool value); };public bool KeepInInsertMode { get; set; }member this.KeepInInsertMode : bool with get, setPublic Property KeepInInsertMode As Boolean속성 값
삽입 작업 후에 삽입 모드를 유지하려면 true이고, 그렇지 않으면 false입니다. 기본값은 false입니다.
예제
다음 예제에서는 사용 하는 방법에 설명 합니다 KeepInInsertMode 속성을 유지는 FormView 컨트롤을 삽입 모드로 삽입 작업 중에 예외가 발생 하는 경우.

설명
기본적으로 FormView 제어가 반환 하 여 지정 된 모드는 DefaultMode 속성입니다. 사용 하 여는 KeepInInsertMode 속성을 지정 하는지 여부를 FormView 삽입 작업 후 컨트롤을 삽입 모드로 유지 해야 합니다. 유지 하는 FormView 삽입 모드에서 컨트롤을이 속성을 설정 true합니다.
참고
상황이 발생 하면 (예: 예외 발생) 정상적인 경우 다르게 동작 하도록 컨트롤을 필요로 하는 경우에이 속성을 사용할 수 해야 합니다. 경우는 FormView 컨트롤 설정, 기본적으로 삽입 모드를 유지 해야 하는 DefaultMode 속성 대신 합니다.
