listView中禁用vridview的前景样式不会改变

Question

我正在尝试更改WPF中禁用的GridView的前景。我的XAML看起来像这样：

<ListView Grid.ColumnSpan="2" Grid.Row="3" ItemsSource="{Binding Lote_Entrada_Viscera.Detalle_Entrada_Viscera}" IsEnabled="False" Foreground="Black">
                    <ListView.ItemContainerStyle>
                        <Style TargetType="{x:Type ListViewItem}" BasedOn="{StaticResource MetroListViewItem}">
                            <Style.Triggers>
                                <DataTrigger Binding="{Binding Completo}" Value="True">
                                    <Setter Property="Background" Value="Green"></Setter>
                                </DataTrigger>
                                <DataTrigger Binding="{Binding Completo}" Value="False">
                                    <Setter Property="Background" Value="Red"></Setter>
                                </DataTrigger>
                                <Trigger Property="IsEnabled" Value="False">
                                    <Setter Property="Foreground" Value="Black" />
                                </Trigger>
                            </Style.Triggers>
                        </Style>
                    </ListView.ItemContainerStyle>
                    <ListView.View>
                        <GridView AllowsColumnReorder="False" ColumnHeaderContainerStyle="{StaticResource GridViewColumnHeaderStyle2}">
                            <GridViewColumn Header="Producto" Width="250" DisplayMemberBinding="{Binding Producto}">
                                <GridViewColumn.CellTemplate>
                                    <DataTemplate>
                                        <TextBlock TextWrapping="Wrap" Text="{Binding}" Width="250"/>
                                    </DataTemplate>
                                </GridViewColumn.CellTemplate>
                            </GridViewColumn>
                            <GridViewColumn Header="Cantidad Lote" DisplayMemberBinding="{Binding Cantidad_Lote}" Width="100"></GridViewColumn>
                            <GridViewColumn Header="Procesados" DisplayMemberBinding="{Binding Capturadas}" Width="75"></GridViewColumn>
                            <GridViewColumn Header="Por Procesar" Width="90" DisplayMemberBinding="{Binding Por_Procesar, StringFormat={}{0:#}}"></GridViewColumn>
                        </GridView>
                    </ListView.View>
                </ListView>

我看到的所有答案是，IneNabled上的触发器应起作用，但它保持默认的灰色。我知道触发作品是因为我测试了更改背景并起作用。关于如何解决此问题的任何想法？

请考虑我正在使用Mahapps样式。

添加带有" Graynormalbrush" x:Key的Brush到<ListView.Resources>：

<ListView Grid.ColumnSpan="2" Grid.Row="3" ItemsSource="{Binding Lote_Entrada_Viscera.Detalle_Entrada_Viscera}" IsEnabled="False" Foreground="Black">
    <ListView.Resources>
        <SolidColorBrush x:Key="GrayNormalBrush" Color="Black" />
    </ListView.Resources>
    <ListView.ItemContainerStyle>
        <Style TargetType="{x:Type ListViewItem}" BasedOn="{StaticResource MetroListViewItem}">
            <Setter Property="Background" Value="Green"></Setter>
            <Style.Triggers>
                <DataTrigger Binding="{Binding Completo}" Value="False">
                    <Setter Property="Background" Value="Red"></Setter>
                </DataTrigger>
            </Style.Triggers>
        </Style>
    </ListView.ItemContainerStyle>
    <ListView.View>
        ...
    </ListView.View>
</ListView>
