C# 将ItemsSource与ResourceDictionary或MergedDictionary一起使用setter属性时的MenuItem样式

我有一个上下文菜单，它是从一个使用XamlReader.Load（）加载的ResourceDictionary中正确设置的样式。我使用的样式键是一个我称之为styleBanner的DynamicSource

在这个上下文菜单中，我有一个名为Skins的菜单项，它也使用saveoverdynamicresourcestylebanner正确设置了样式。但是此菜单项将其子菜单项数据绑定到数据上下文视图模型中的ItemsSource，这也可以正常工作

我的问题是子菜单项的样式不正确

以下是工作原理，但根本不需要设置样式：

<Window.ContextMenu>
    <ContextMenu DataContext="TimersHostViewModel" Name="TimersHostContextMenu" Style="{DynamicResource styleBanner}">
        <MenuItem Name="Skins" Header="Skins" ItemsSource="{Binding Source={StaticResource TimersHostViewModel}, Path=Skins}" Style="{DynamicResource styleBanner}">
            <MenuItem.ItemContainerStyle>
                <Style TargetType="MenuItem">
                    <Setter Property="Header" Value="{Binding Path=SkinName}"/>
                    <Setter Property="Command" Value="{Binding Source={StaticResource TimersHostViewModel}, Path=TimersHostContextMenuClickCommand}"/>
                    <Setter Property="CommandParameter" Value="{Binding Path=SkinName}"/>
                </Style>
            </MenuItem.ItemContainerStyle>
        </MenuItem>
    </ContextMenu>
</Window.ContextMenu>

这里有一件事我试过了，我试着添加以下行：

<Setter Property="Style" Value={DynamicResource styleBanner}"/>

不能在样式中设置样式属性

在样式（例如ContextMenuStyle）中，将StyleBanner设置为
ItemContainerStyle

例如，将您的样式名称命名为ContextMenuStyle，并将其ItemContainer样式设置为
StyleBanner

<Style x:Key="ContextMenuStyle" TargetType="MenuItem">
    <Setter Property="Header" Value="{Binding Path=SkinName}"/>
    <Setter Property="Command" Value="{Binding Source={StaticResource TimersHostViewModel}, Path=TimersHostContextMenuClickCommand}"/>
    <Setter Property="CommandParameter" Value="{Binding Path=SkinName}"/>
    <Setter Property="ItemContainerStyle" Value="{DynamicResource styleBanner}"/>
</Style>

您可以使用“BasedOn”属性：

<MenuItem.ItemContainerStyle>
  <Style BasedOn="{StaticResource ISAMenu}" TargetType="MenuItem">
      <Setter Property="Command" Value="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=MenuItem}, Path=DataContext.ChangeLanguageCommand}" />
      <Setter Property="CommandParameter" Value="{Binding}" />
  </Style>
</MenuItem.ItemContainerStyle>



然后在App.xaml中，只需引用字典即可

<ResourceDictionary.MergedDictionaries>
   <ResourceDictionary Source="Assets/ResourceDictionaries/NavBarMenu.xaml" />
 </ResourceDictionary.MergedDictionaries>



最后在NavBarMenu.xaml中

<Style x:Key="ISAMenu" TargetType="{x:Type MenuItem}">



这是一个老问题，但我花了一些时间寻找另一个干净的解决方案，因此我希望它能帮助别人。
您使用的是哪个.net框架？我知道，我需要的是ItemContainerStyle。事实上，我看到了其他一些东西，它实际上一直在工作，除了ResourceDictionary中的子菜单项background。我会更新这个问题。这是一个新的信息。这看起来真的很有希望实现这一目标。事实上，我很难找到这个问题的正确解决方案，并将其推广到全局蒙皮解决方案，这是我一起放弃XAML的原因之一。的确，我希望它能帮助其他人-D
