我有代码:
<ListBox Style="{StaticResource DeviceListBox}"
ItemsSource="{Binding MeterList, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type UserControl}}}"
SelectedItem="{Binding CurrentMeter, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type UserControl}}}"
ItemContainerStyleSelector="{StaticResource DeviceListItemStyleSelector}">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<TextBlock Style="{StaticResource DeviceListText}" Text="{Binding Name}" />
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
我使用ItemContainerStyleSelector="{StaticResource DeviceListItemStyleSelector}"
更改每个列表框项目中的背景颜色(例如黑色或银色,请参阅 - http://msdn.microsoft.com/en-us/library/system.windows.controls.styleselector.aspx)。它有效。但是,如果我在ItemContainerStyle="{StaticResource DeviceListItemStyle}"
中添加DeviceListItemStyle
来创建一些触发器等,则DeviceListItemStyleSelector
不起作用。请帮帮我!)

ItemContainerStyleSelector
根据某些逻辑选择样式,因此显然手动设置样式将覆盖您的选择器应用的样式。
为什么不在ItemContainerStyle
设置背景颜色?
<Style x:Key="DeviceListItemStyle" TargetType="{x:Type ListBoxItem}">
<Setter Property="Background" Value="Black" />
<Style.Triggers>
<DataTrigger Binding="{Binding IsSilver}" Value="True">
<Setter Property="Background" Value="Silver" />
</DataTrigger>
</Style.Triggers>
</Style>
