설명
AccessDataSource 클래스는 Microsoft Access 데이터베이스와 함께 사용할 수 있는 데이터 소스 컨트롤입니다. 해당 기본 클래스 SqlDataSource와 마찬가지로 AccessDataSource 컨트롤은 SQL 쿼리를 사용하여 데이터 검색을 수행합니다.
AccessDataSource 컨트롤의 고유한 특징 중 하나는 ConnectionString 속성을 설정하지 않는다는 것입니다. DataFile 속성을 사용하여 Access .mdb 파일의 위치만 설정하면 AccessDataSource가 데이터베이스에 대한 기본 연결을 처리합니다. Access 데이터베이스는 웹 사이트의 App_Data 디렉터리에 배치해야 하며 상대 경로(예: ~/App_Data/Northwind.mdb)를 사용하여 참조되어야 합니다. 이 위치를 사용하면 클라이언트 웹 브라우저에서 직접 요청할 경우에는 데이터 파일이 제공되지 않기 때문에 데이터 파일의 보안을 강화할 수 있습니다.
AccessDataSource 클래스에는 ConnectionString 속성을 설정할 수 없기 때문에 사용자 이름 또는 암호로 보호되는 Access 데이터베이스에 대한 연결은 지원되지 않습니다. Access 데이터베이스가 사용자 이름 또는 암호로 보호되는 경우에는 완전한 연결 문자열을 지정할 수 있도록 SqlDataSource 컨트롤을 사용하여 데이터베이스에 연결해야 합니다.
데이터 바인딩된 컨트롤의 DataSourceID 속성을 사용하여 데이터 바인딩된 컨트롤을 AccessDataSource에 바인딩합니다. 데이터 바인딩된 컨트롤을 데이터 소스 컨트롤에 바인딩하는 방법에 대한 자세한 내용은 데이터 소스 컨트롤을 사용하여 데이터에 바인딩을 참조하십시오.
AccessDataSource 컨트롤의 사용에 대한 자세한 내용은 AccessDataSource 웹 서버 컨트롤 개요를 참조하십시오.
예제
다음 코드 예제에서는 GridView 컨트롤을 사용한 일반적인 표시 및 업데이트 시나리오를 보여 줍니다. SelectCommand 속성이 적절한 SQL 쿼리에 설정되고 Northwind 데이터베이스의 데이터가 GridView 컨트롤에 표시됩니다. 이 예제에는 UpdateCommand도 지정되고 AutoGenerateEditButton이 true로 설정되었기 때문에 별도의 코드 추가 없이 레코드를 편집하고 업데이트할 수 있습니다. GridView 컨트롤은 UpdateParameters 컬렉션에 매개 변수를 추가하는 작업을 처리합니다. 이때 GridView는 BoundField 개체의 매개 변수를 먼저 전달하고 그 다음으로 DataKeyNames 속성에 지정된 필드 값을 전달합니다. GridView는 Update 메서드를 자동으로 호출합니다. 매개 변수의 순서를 지정하려면 AccessDataSource 개체에 UpdateParameters 컬렉션을 명시적으로 지정하면 됩니다.
