wpf - 更改选定列表框项目的背景颜色

Question

这是迄今为止我的 XAML。

<ScrollViewer Grid.Column="1" Grid.RowSpan="2">

    <ListBox   Background="Black" ItemsSource="{Binding Path=ActiveLog}" >
        <ListBox.ItemTemplate>
            <DataTemplate>
                <Grid Background="Black">
                    <Grid.ColumnDefinitions>
                        <ColumnDefinition Width="200"></ColumnDefinition>
                        <ColumnDefinition Width="*"></ColumnDefinition>
                    </Grid.ColumnDefinitions>
                    <Grid.RowDefinitions>
                        <RowDefinition></RowDefinition>
                        <RowDefinition></RowDefinition>
                    </Grid.RowDefinitions>
                    <TextBlock Grid.Column="0" Grid.Row="0" Foreground="White">
                        <TextBlock >Date:</TextBlock>
                        <TextBlock  Text="{Binding Path=LogDate}"/>
                    </TextBlock>
                    <TextBlock Grid.Column="1" Grid.Row="0" Foreground="White">
                        <TextBlock >Severity:</TextBlock>
                        <TextBlock  Text="{Binding Path=Severity}"/>
                    </TextBlock>
                    <TextBlock Grid.Column="0" Grid.ColumnSpan="2" Grid.Row="1" Foreground="LightGray" Text="{Binding Path=Message}"></TextBlock>
                </Grid>
            </DataTemplate>
        </ListBox.ItemTemplate>
        <ListBox.Template>
            <ControlTemplate>
                <StackPanel Background="Black" IsItemsHost="True" >
                </StackPanel>
            </ControlTemplate>
        </ListBox.Template>

    </ListBox>
</ScrollViewer>

唯一的问题是所选项目的右侧有一个蓝色框。我认为有一种方法可以更改选择颜色，但我找不到它。

Answer 1

<UserControl.Resources>
    <Style x:Key="myLBStyle" TargetType="{x:Type ListBoxItem}">
        <Style.Resources>
            <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}"
                             Color="Transparent"/>
        </Style.Resources>
    </Style>
</UserControl.Resources> 

和

<ListBox ItemsSource="{Binding Path=FirstNames}"
         ItemContainerStyle="{StaticResource myLBStyle}">  

您只需覆盖列表框项的样式(请参阅:TargetType 是 ListBoxItem)
