FormView.InsertItem(Boolean) 메서드

정의

데이터 소스에 현재 레코드를 삽입합니다.

public:
 virtual void InsertItem(bool causesValidation);
public virtual void InsertItem (bool causesValidation);
abstract member InsertItem : bool -> unit
override this.InsertItem : bool -> unit
Public Overridable Sub InsertItem (causesValidation As Boolean)

매개 변수

causesValidation
Boolean

메서드가 호출될 때 페이지 유효성 검사를 수행하려면 true이고, 그렇지 않으면 false입니다.

예외

FormView 컨트롤이 삽입 모드에 있지 않은 상태에서 이 메서드를 호출한 경우

또는

DataSourceView 컨트롤과 연결된 FormView 개체가 null인 경우

예제

다음 예제에서는 메서드를 사용 하 여 InsertItem 프로그래밍 방식으로 현재 레코드를 삽입 하는 FormView 방법을 보여 줍니다는 데이터 원본의 컨트롤입니다.

설명

컨트롤이 FormView 삽입 모드인 경우 메서드를 InsertItem 사용하여 데이터 원본에 현재 레코드를 프로그래밍 방식으로 삽입합니다. 이 메서드는 일반적으로 페이지의 다른 컨트롤과 같이 컨트롤 외부에서 FormView 현재 레코드를 삽입해야 하는 경우에 사용됩니다.

참고

FormView 메서드가 호출될 때 컨트롤이 삽입 모드여야 합니다. 그렇지 않으면 가 HttpException throw됩니다.

삽입 작업 전에 페이지 유효성 검사를 수행할지 여부를 지정하려면 매개 변수를 causesValidation 사용합니다. 이 메서드를 호출하면 및 ItemInserting 이벤트도 발생합니다ItemInserted.
