각 응용 프로그램을 나타내는 여러 sqlserver 테이블이 있습니다. 이 모든 테이블을 mantain (보기/편집/삽입/삭제)해야합니다. 이 응용 프로그램 테이블에는 모두 ID라는 기본 기본 키 열이 있습니다.ASP.NET 동적 목록 뷰 웹 응용 프로그램
이 작업을 수행하기 위해 이러한 응용 프로그램 테이블을 유지 관리하기위한 페이지를 빌드하는 기본 SqlServer 구성 테이블을 만들었습니다.
dbo.ApplGenerator_Applications : 이 테이블은 웹 응용 프로그램의보기 창에서 데이터를 정렬하는 추가 필드와 실제 SQLSERVER 테이블에 응용 프로그램을 매핑합니다.
CREATE TABLE [dbo].[ApplGenerator_Applications](
[ApplicationName] [varchar](50) NOT NULL,
[RealTable] [varchar](255) NOT NULL,
[OrderBy] [varchar](255) NOT NULL,
[Desc_OrderBy] [varchar](255) NOT NULL
)
기본 키의 이름과 유형이 항상 같기 때문에이 정보를 응용 프로그램 구성 테이블에 추가 할 필요가 없습니다.

문제는 아이콘 (데이터 ListView ItemTemplate의 ImageButton 컨트롤)을 삭제하기 위해 아이콘을 클릭해도 삭제할 코드와 데이터 목록 뷰가 모두 다시로드되지 않습니다.
내가 ASP.NET에 새로 온 사람과 확실히 내가 (매우) 잘못 somethig에하고 있어요
. 이 문제를 해결하는 방법에 대한 아이디어가 없습니다. 누군가 도움을 줄 수 있습니까?감사합니다,
