ICachedReport 인터페이스

이 인터페이스는 구현 클래스를 Crystal Reports SDK를 사용하여 ASP.NET Cache 개체로 캐시할 수 있는 것으로 식별합니다.

이 형식의 멤버 목록을 보려면 ICachedReport 멤버를 참조하십시오.

ICachedReport

[Visual Basic]

Public Interface ICachedReport
   Inherits System.Object

[C#]

public interface ICachedReport : System.Object

설명

미리 만들어진 캐싱 메커니즘을 사용하려면 사용자의 고유 클래스에 이 인터페이스를 구현합니다. 사용자가 구현하는 메서드 및 속성은 보고서를 캐싱하는 데 필요한 정보를 검색하기 위해 ReportDocument 개체 모델에 의해 호출됩니다. 클래스의 인스턴스를 CrystalReportViewer 컨트롤의 ReportSource 속성으로 설정하여 캐싱을 활성화합니다.

다음 예제는 ICachedReport 인터페이스를 구현하는 클래스를 만듭니다.
