방법: Windows Forms BindingNavigator 컨트롤을 사용하여 DataSet를 통해 이동

  • 아티클

데이터 기반 애플리케이션을 빌드할 때 사용자에게 데이터 컬렉션을 표시해야 하는 경우가 많습니다. BindingSource 구성 요소와 더불어 BindingNavigator 컨트롤은 컬렉션을 탐색하고 항목을 순차적으로 표시하기 위한 편리하고 확장 가능한 솔루션을 제공합니다.

예제

다음 코드 예제에서는 BindingNavigator 컨트롤을 사용하여 데이터를 탐색하는 방법을 보여 줍니다. 집합은 TextBox 컨트롤에 BindingSource 구성 요소로 바인딩된 DataView에 포함되어 있습니다.

참고

암호와 같은 중요한 정보를 연결 문자열 내에 저장하면 애플리케이션 보안 문제가 발생할 수 있습니다. 데이터베이스 액세스를 제어할 경우에는 통합 보안이라고도 하는 Windows 인증을 사용하는 방법이 더 안전합니다. 자세한 내용은 연결 정보 보호를 참조하세요.
