방법: ColumnDefinitionsCollections 및 RowDefinitionsCollections를 사용하여 열 및 행 조작

이 예제에서는 ColumnDefinitionCollectionRowDefinitionCollection 클래스의 메서드를 사용하여 행 또는 열의 내용을 추가, 삭제, 계산하는 등의 작업을 수행하는 방법을 보여 줍니다. 예를 들어 ColumnDefinition 또는 RowDefinition에 포함된 항목을 Add, Clear 또는 Count할 수 있습니다.

예제

다음 예제에서는 grid1Name을 사용하여 Grid 요소를 만듭니다. Grid에는 각각 다른 수집 메서드에 의해 제어되는 Button 요소를 보유하는 StackPanel이 포함됩니다. Button을 클릭하면 코드 숨김 파일에서 메서드 호출이 활성화됩니다.

이 예제에서는 각각 XAML(Extensible Application Markup Language) 파일의 Click 이벤트에 해당하는 일련의 사용자 지정 메서드를 정의합니다. 행 및 열을 추가 또는 제거하고 행 및 열의 총 수를 계산하는 등 여러 가지 방법으로 Grid의 열 및 행 수를 변경할 수 있습니다. ArgumentOutOfRangeExceptionArgumentException 예외를 방지하기 위해 RemoveRange 메서드에서 제공하는 오류 검사 기능을 사용할 수 있습니다.
