저는 WPF 응용 프로그램을 만들고 있는데, 콤보 상자의 App.XAML에 정의 된 컨트롤 템플릿이 있습니다.WPF 컨트롤 템플릿이 렌더링 된 첫 번째 항목에 적용되지 않습니다.
응용 프로그램을 시작할 때 렌더링되는 첫 번째 콤보 상자는 컨트롤 템플릿에 정의 된 스타일을 사용하지 않지만 다른 모든 것은 수행합니다. 또한 첫 번째 콤보 상자에는 스타일이없는 첫 번째 항목이 있고 나머지 항목에는 해당 콤보 상자와 다른 항목의 스타일이 지정되어 있습니다.
무엇이 누락 되었습니까?

일부 XAML을 표시 할 수 있습니까? – Nitesh
미안하지만, 나는 내 마음을 잃었다. app.xaml이 지금은 – VARAK
입니다. ComboBox 컨트롤의 나머지 부분에 적용되므로 ControlTemplate에 문제가있는 것처럼 보이지 않으므로 괜찮아 보입니다. ComboBox 컨트롤을 만들 위치를 XAML로 표시하십시오. – Nitesh
