방법: Windows Forms DataGridView 컨트롤에 데이터 바인딩

아티클
08/09/2011

DataGridView 컨트롤은 표준 Windows Forms 데이터 바인딩 모델을 지원하므로 다양한 데이터 소스에 바인딩됩니다. 그러나, 대부분의 환경에서는 데이터 소스와의 상호 작용에 대한 세부 사항을 관리하는 BindingSource 구성 요소에 바인딩합니다. BindingSource 구성 요소는 Windows Forms 데이터 소스를 나타낼 수 있으며 이를 사용하여 데이터 위치를 매우 융통성 있게 선택하거나 수정할 수 있습니다. DataGridView 컨트롤에 지원되는 데이터 소스에 대한 자세한 내용은 DataGridView 컨트롤 개요(Windows Forms)를 참조하십시오.

Visual Studio에서는 이 작업을 폭넓게 지원합니다. 자세한 내용은 다음을 참조하십시오. 방법: 디자이너를 사용하여 Windows Forms DataGridView 컨트롤에 데이터 바인딩 및 방법: 디자이너를 사용하여 Windows Forms DataGridView 컨트롤에 데이터 바인딩 및 방법: 디자이너를 사용하여 Windows Forms DataGridView 컨트롤에 데이터 바인딩 및 방법: 디자이너를 사용하여 Windows Forms DataGridView 컨트롤에 데이터 바인딩.

절차

DataGridView 컨트롤을 데이터에 연결하려면

데이터베이스에서의 데이터 검색에 대한 세부 사항을 처리하도록 메서드를 구현합니다. 다음 코드 예제에서는 SqlDataAdapter 구성 요소를 초기화하는 GetData 메서드를 구현하여 DataTable을 채웁니다. 그런 다음 DataTable이 BindingSource 구성 요소에 바인딩됩니다. connectionString 변수를 데이터베이스에 적합한 값으로 설정해야 합니다. Northwind SQL Server 샘플 데이터베이스가 설치되어 있는 서버에 액세스할 수 있어야 합니다.

보안

연결 문자열에 중요한 정보(예: 암호)를 저장하면 응용 프로그램 보안 문제가 발생할 수 있습니다. 데이터베이스 액세스를 제어할 경우에는 통합 보안이라고도 하는 Windows 인증을 사용하는 방법이 더 안전합니다. 자세한 내용은 연결 정보 보호(ADO.NET)를 참조하십시오.
