Question

How can I strike through all textblocks inside my WPF listview? Right now I’ve defined a style that I have to apply to each textblock. It looks like this

    <Style x:Key="orderDetailsTextBlock" TargetType="TextBlock" >
        <Style.Triggers>
            <DataTrigger Binding="{Binding Status}" Value="Failed">
                <Setter Property="TextDecorations" Value="Strikethrough" />
            </DataTrigger>
        </Style.Triggers>
    </Style>

What I want is to be able to apply this once inside the ListViewItem Style block.

I tried to do it like this

    <Style x:Key="ordersListViewItemStyle" TargetType="{x:Type ListViewItem}">
        <Style.Triggers>
            <DataTrigger Binding="{Binding Status}" Value="Failed">
                <Setter Property="TextBlock.TextDecorations" Value="Strikethrough" />
            </DataTrigger>
        </Style.Triggers>           
    </Style>

But this doesn’t work. Any help will appreciated.

Update
I updated the ListView’s XAML as follows

    <ListView x:Name="orderDetails" AlternationCount="2" ItemContainerStyle="{StaticResource ordersListViewItemStyle}" >
    <ListView.Resources>
        <Style TargetType="TextBlock">
            <Style.Triggers>
                <DataTrigger Binding="{Binding Status}" Value="Failed">
                    <Setter Property="TextDecorations" Value="Strikethrough" />
                </DataTrigger>
            </Style.Triggers>
        </Style>
    </ListView.Resources>
    <ListView.View>
        <GridView>
            <GridViewColumn Width="100" Header="Статус" >
                <GridViewColumn.CellTemplate>
                    <DataTemplate>
                        <TextBlock 
                                            Text="{Binding Path=Status, Mode=OneWay, UpdateSourceTrigger=PropertyChanged}"
                                            ToolTip="{Binding Path=Message, Mode=OneWay, UpdateSourceTrigger=PropertyChanged}"
                                            TextAlignment="Center" />
                    </DataTemplate>
                </GridViewColumn.CellTemplate>
            </GridViewColumn>
        </GridView>
    </ListView.View>
</ListView>

Nothing happens. What have I done wrong?

You can define the Style inside your ListView.Resources without a Key, and it’s scope will be restricted to all TextBlocks inside that particular ListView.

For instance:

<ListView x:Name="MyListView">
    <ListView.Resources>
        <Style TargetType="TextBlock">
            <!-- Style specific content -->
        </Style>
    </ListView.Resources>
    <!-- ListView content -->
</ListView>
