Expander ControlTemplate 예제

  • 아티클

업데이트: 2007년 11월

WPF(Windows Presentation Foundation)의 컨트롤에는 해당 컨트롤의 시각적 트리가 포함된 ControlTemplate이 있습니다. 컨트롤의 ControlTemplate을 수정하면 해당 컨트롤의 구조와 모양을 변경할 수 있습니다. 컨트롤의 시각적 트리 부분만 바꿀 수 있는 방법은 없습니다. 즉, 컨트롤의 시각적 트리를 변경하려면 컨트롤의 Template 속성을 새로운 전체 ControlTemplate으로 설정해야 합니다.

이 항목에서는 WPFExpander 컨트롤의 ControlTemplate을 보여 줍니다.

이 항목에는 다음 단원이 포함되어 있습니다.

사전 요구 사항

이 항목의 예제를 실행하려면 WPF 응용 프로그램 작성 방법을 알고 있어야 합니다. 자세한 내용은 Windows Presentation Foundation 시작을 참조하십시오. WPF에서 스타일이 사용되는 방식도 알고 있어야 합니다. 자세한 내용은 스타일 지정 및 템플릿을 참조하십시오.

Expander ControlTemplate 예제

이 예제에는 기본적으로 Expander의 ControlTemplate에 정의된 요소가 모두 포함되어 있지만 특정 값은 예제로만 간주해야 합니다.
