RowCreated 이벤트를 발생시킵니다.
protected:
virtual void OnRowCreated(System::Web::UI::WebControls::GridViewRowEventArgs ^ e);
protected virtual void OnRowCreated (System.Web.UI.WebControls.GridViewRowEventArgs e);
abstract member OnRowCreated : System.Web.UI.WebControls.GridViewRowEventArgs -> unit
override this.OnRowCreated : System.Web.UI.WebControls.GridViewRowEventArgs -> unit
Protected Overridable Sub OnRowCreated (e As GridViewRowEventArgs)
매개 변수
이벤트 데이터가 들어 있는 GridViewRowEventArgs입니다.
예제
다음 예제에서는 이벤트에 대 한 이벤트 처리 메서드를 제공 하는 방법을 보여 줍니다 RowCreated . 행을 만들 때 해당 인덱스는 새 행에 CommandArgument 포함된 컨트롤의 LinkButton 속성에 저장됩니다. 이렇게 하면 사용자가 명령 단추를 클릭할 때 행의 인덱스를 확인할 수 있습니다.

설명
전에 GridView 컨트롤을 렌더링을 GridViewRow 컨트롤의 각 행에 대 한 개체를 만들어야 합니다. 이벤트는 RowCreated 컨트롤의 각 행을 GridView 만들 때 발생합니다. 이렇게 하면 이 이벤트가 발생할 때마다 행에 사용자 지정 콘텐츠를 추가하는 등 사용자 지정 루틴을 수행하는 이벤트 처리 메서드를 제공할 수 있습니다.
이벤트가 발생하면 대리자를 통해 이벤트 처리기가 호출됩니다. 자세한 내용은 이벤트 처리 및 발생합니다.
또한 OnRowCreated 메서드를 사용하면 파생 클래스가 대리자를 연결하지 않고도 이벤트를 처리할 수 있습니다. 이는 파생 클래스에서 이벤트를 처리하는 기본 방법입니다.
상속자 참고
파생 클래스에서 OnRowCreated(GridViewRowEventArgs)를 재정의하는 경우 등록된 대리자가 이벤트를 받도록 기본 클래스의 OnRowCreated(GridViewRowEventArgs) 메서드를 호출해야 합니다.
