DataTable.RowChanged 이벤트
DataRow를 성공적으로 변경한 후 발생합니다.
네임스페이스: System.Data
어셈블리: System.Data(system.data.dll)
구문
‘선언
Public Event RowChanged As DataRowChangeEventHandler
‘사용 방법
Dim instance As DataTable
Dim handler As DataRowChangeEventHandler
AddHandler instance.RowChanged, handler
public event DataRowChangeEventHandler RowChanged
public:
event DataRowChangeEventHandler^ RowChanged {
void add (DataRowChangeEventHandler^ value);
void remove (DataRowChangeEventHandler^ value);
}
/** @event */
public void add_RowChanged (DataRowChangeEventHandler value)
/** @event */
public void remove_RowChanged (DataRowChangeEventHandler value)
JScript에서는 이벤트를 사용할 수 있지만 새로 선언할 수는 없습니다.
