ListConBox에 item 컨테이너 스타일이 있고이 스타일로 배경색이 있습니다 (녹색이라고도 함). MVVM에서 배경색을 변경하고 싶습니다. 일부 특정 조건에서 색상이 변경되며, 그렇지 않으면 기본 색상 (예 : 녹색)이 적용됩니다.ListBox의 ItemContainerStyle 변경 WPVM의 MVVM MVVM 패턴
<ListBox x:Name="lst1" ItemsSource="{Binding DataSource}" ScrollViewer.HorizontalScrollBarVisibility="Auto" ScrollViewer.VerticalScrollBarVisibility="Disabled" Style="{DynamicResource StepListBox}" ItemContainerStyle="{DynamicResource ListBoxItemStyle}" Margin="-10,0,0,0">

가 어떻게 내 뷰 모델에서 변경할 수있는 별도의 XAML 파일에 정의 된 내 ListboxItemStyle은 무엇입니까?
당신은 당신의 ViewModel 층에 부울에 스타일에 DataTrigger가 필요합니다
'ItemContainerStyle'은 UI 요소이며 MVVM과 전혀 관련이 없습니다. 아마도 제목이나 질문을 조정해야합니까? – Sheridan
