표보기를 사용하여 여러 테이블 (Empdetail, Department, Country, State, City, Qualification)의 조인을 표시하려고합니다. 기본 테이블 (Empdetail)에는 테이블에있는 기본 키 ID를 참조하는 다른 ID (예 : DeptID)가 있습니다. 부서 (및 기타 필드)가 GridView를 업데이트하는 동안 드롭 다운 선택 항목으로 표시되기를 원하지만 드롭 다운 목록을 채우고 편집 버튼을 실행하는 동안 문제를 직면하고 있습니다. 다음은 코드입니다.Gridview의 편집 단추가 작동하지 않습니다.

}참고 : - 광범위하게 여러 사이트에서 검색 했으므로 나를 링크로 안내하는 대신 정확한 문제를 말할 수 있다면 정말 감사하겠습니다. 나는 Gridview의 개념에 익숙하지 않으므로 열린 마음으로 코드를 비평 해주십시오. 미리 감사드립니다
감사합니다. 나는 그러한 통제를 알지 못했다. –
