배열 및 CollectionView

그리드의 itemsSource 속성을 일반 JavaScript 배열로 설정하면 내부 CollectionView가 자동으로 생성되어 데이터 소스로 사용되므로, CollectionView를 직접 만들지 않아도 정렬 및 편집 기능을 사용할 수 있습니다. 이 내부 뷰는 그리드의 collectionView 속성을 통해 노출되며, 추가 기능이 필요한 경우에 사용할 수 있습니다. 예를 들어 아래 그리드는 일반 배열에 바인딩되어 있으며, 그리드의 collectionView 속성을 사용하여 현재 선택된 항목을 표시합니다.
