GridView 컨트롤에서 행을 만들면 이 이벤트가 발생합니다.
public:
event System::Web::UI::WebControls::GridViewRowEventHandler ^ RowCreated;public event System.Web.UI.WebControls.GridViewRowEventHandler RowCreated;member this.RowCreated : System.Web.UI.WebControls.GridViewRowEventHandler Public Custom Event RowCreated As GridViewRowEventHandler 이벤트 유형
예제
다음 예제에서는 사용 하는 RowCreated 방법에 설명 합니다 행에 포함 된 컨트롤의 속성에 CommandArgument 생성 되는 행의 인덱스를 LinkButton 저장 하는 이벤트입니다. 이렇게 하면 사용자가 단추를 클릭할 때 컨트롤이 포함된 LinkButton 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.
GridViewRowEventArgs 개체는 생성되는 행의 속성에 액세스할 수 있는 이벤트 처리 메서드에 전달됩니다. 행의 특정 셀에 액세스하려면 개체의 CellsGridViewRowEventArgs 속성을 사용합니다. 속성을 사용하여 만들 행 유형(머리글 행, 데이터 행 등)을 RowType 확인할 수 있습니다.
이벤트를 처리 하는 방법에 대 한 자세한 내용은 참조 하세요. 이벤트 처리 및 발생합니다.
