@bardev는 좋은 솔루션을 제공하지만 안타깝게도 모든 경우에 이상적이지는 않습니다. 내 것이 그들 중 하나였습니다.
VS 2013에서 웹 사이트에서 WebForms를 사용하고 있습니다 (다시는 웹 사이트를 사용하지 않겠다고 맹세합니다. PITA).
Razor 제안을 시도했지만 내 웹 사이트는 IDE가 MVC 프로젝트에서 제공하는 가장 중요한 IntelliSense를 얻지 못했습니다. 또한 UserControl을위한 완벽한 장소 인 템플릿에 디자이너를 사용하고 싶습니다.
다시 Razor의 Nix.
그래서 대신이 작은 프레임 워크를 생각해 냈습니다 (UserControl의 경우 @mun, Strong Typing의 경우 @imatoria에 대한 모자 팁). 내가 볼 수있는 유일한 잠재적 문제 지점은 .ASCX 파일 이름을 클래스 이름과 동기화되도록주의해야한다는 것입니다. 길을 잃으면 런타임 오류가 발생합니다.
FWIW : 테스트에서 적어도 RenderControl () 호출은 Page 컨트롤을 좋아하지 않으므로 UserControl을 사용했습니다.
여기에 모든 것을 포함 시켰습니다. 내가 빠진 것이 있으면 알려주세요.
