안녕하세요 데이터 테이블에 문제가 있습니다. 사용자가 button을 클릭 할 때마다 데이터 테이블에 새로운 행을 삽입하고 싶습니다. 저는 10 개의 버튼을 가지고 있는데, 버튼 1을 클릭하면 새로운 행이 삽입됩니다. 그러나 버튼 2를 클릭하면 기존 행이 새로운 행으로 바뀝니다. 도움!다른 단추에서 dataTable의 행 추가 asp.net]
여기에 내가 버튼에서 새 행을 추가하기위한 메소드를 호출 ////이 행을 추가

데이터 행에 고유 ID와 같은 것이 있어야합니다. 그래서 각 행을 고유하게 식별 할 수 있습니다. 그러면 button2에서 클릭 한 행을 대체 할 수 있습니다. button2 – tarzanbappa
