방법: Windows Forms DataGridView 컨트롤에서 내용이 변경되는 경우 자동으로 셀 크기 조정
콘텐츠가 변경될 때마다 행, 열 및 헤더 크기를 자동으로 조정하여 셀 값이 잘리지 않고 항상 셀에 표시되도록 DataGridView 컨트롤을 구성할 수 있습니다.
새 크기를 결정하는 데 사용되는 셀을 제한하는 많은 옵션이 있습니다. 예를 들어 현재 표시된 행의 값만 기준으로 열 너비를 자동으로 조정하도록 컨트롤을 구성할 수 있습니다. 그러면 다수의 행으로 작업할 때 비효율성을 방지할 수 있지만 이 경우 AutoResizeColumns 와 같은 크기 조정 메서드를 사용하여 선택 시 크기를 조정하는 것이 좋습니다.
자동 크기 조정에 대한 자세한 내용은 Sizing Options in the Windows Forms DataGridView Control을(를) 참조하십시오.
다음 코드 예제에서는 자동 크기 조정에 사용할 수 있는 옵션을 보여 줍니다.
