Question

我有以下xaml：

<ListView.ItemTemplate>
<DataTemplate>
    <Border x:Name="SetBorder" Background="Transparent">
        <Grid Margin="5" Width="130">
            <Grid.RowDefinitions>
                <RowDefinition Height="30"/>
                <RowDefinition Height="Auto"/>
            </Grid.RowDefinitions>
            <Image Source="{Binding Path=Code, Converter={StaticResource SetCodeToImageConverter}}" MaxWidth="105">
                <Image.Style>
                    <Style>
                        <Style.Triggers>
                            <DataTrigger Binding="{Binding ElementName=SetBorder, Path=Selector.IsSelectionActive}" Value="True">
                                <Setter Property="Image.Opacity" Value="1" />
                            </DataTrigger>
                            <DataTrigger Binding="{Binding ElementName=SetBorder, Path=IsMouseOver}" Value="True">
                                <Setter Property="Image.Opacity" Value="1" />
                            </DataTrigger>
                            <DataTrigger Binding="{Binding ElementName=SetBorder, Path=IsMouseOver}" Value="False">
                                <Setter Property="Image.Opacity" Value="0.5" />
                            </DataTrigger>
                        </Style.Triggers>
                    </Style>
                </Image.Style>
            </Image>
            <TextBlock Grid.Row="1" HorizontalAlignment="Center" VerticalAlignment="Center" 
                       Text="{Binding Path=Name}" TextWrapping="WrapWithOverflow" MaxWidth="120">
            </TextBlock>
        </Grid>
    </Border>
</DataTemplate>

我希望当鼠标结束时（该部分有效）以及选择该项目时该图像的不透明度设置为1（该部分不起作用）。有什么想法吗？

试试这个

<DataTrigger Binding="{Binding RelativeSource={RelativeSource AncestorType=  {x:Type ListBoxItem}, Path=IsSelected}" Value="True">
   <Setter Property="Image.Opacity" Value="1" />
</DataTrigger>

我没有尝试过，但它应该有效

在列表视图
