설명

설정 합니다 Text 속성을 null 이거나 빈 문자열 ("") 설정의 SelectedIndex -1로.Setting the Text property to null or an empty string ("") sets the SelectedIndex to -1. 설정 합니다 Text 속성에 있는 값을는 Items 컬렉션 집합은 SelectedIndex 해당 항목의 인덱스.Setting the Text property to a value that is in the Items collection sets the SelectedIndex to the index of that item. 설정 합니다 Text 콜렉션에 있지 않은 값으로 속성을 SelectedIndex 변경 되지 않은 합니다.Setting the Text property to a value that is not in the collection leaves the SelectedIndex unchanged.
