DataGrid.CurrentPageIndex 속성
정의
중요
일부 정보는 릴리스되기 전에 상당 부분 수정될 수 있는 시험판 제품과 관련이 있습니다. Microsoft는 여기에 제공된 정보에 대해 어떠한 명시적이거나 묵시적인 보증도 하지 않습니다.
현재 표시된 페이지의 인덱스를 가져오거나 설정합니다.
public:
property int CurrentPageIndex { int get(); void set(int value); };

public int CurrentPageIndex { get; set; }
[System.ComponentModel.Browsable(false)]
public int CurrentPageIndex { get; set; }
[<System.ComponentModel.Bindable(true)>]
[<System.ComponentModel.Browsable(false)>]
member this.CurrentPageIndex : int with get, set
[<System.ComponentModel.Browsable(false)>]

Public Property CurrentPageIndex As Integer
속성 값
현재 표시된 페이지의 인덱스(0부터 시작)입니다.
- 특성
예외
지정된 페이지의 인덱스가 음수 값인 경우
예제
다음 코드 예제를 사용 하는 방법에 설명 합니다 CurrentPageIndex 속성을 프로그래밍 방식으로 표시할 페이지를 제어는 DataGrid 컨트롤입니다.
