WPF ListView Highlight Color don't change

Question

I have a ListView with three TextBlock for each Item. The first one has the default color (black) and the others has the property Foreground set to gray.

When I select an item the color of the first TextBlock becomes blue but the others stay gray and are hard to read.

I want that all the text become white color when the item is selected. How I do that ?

Edit : My style :

 <UserControl.Resources>
        <Style TargetType="{x:Type ListViewItem}">
            <Style.Triggers>
                <Trigger Property="IsSelected" Value="True">
                    <Setter Property="Foreground" Value="White"/>
                </Trigger>
            </Style.Triggers>
        </Style>
    </UserControl.Resources>

My ListView

        <ListView  x:Name="lvResultat"  Grid.Row="0" Grid.Column="1" Background="{x:Null}"  
                      Margin="4"                       
                      HorizontalContentAlignment="Stretch"
                           ScrollViewer.VerticalScrollBarVisibility="Auto"
                      ScrollViewer.HorizontalScrollBarVisibility="Disabled"
                      IsSynchronizedWithCurrentItem="True"    

                      ItemsSource="{Binding ResultatsRecherche}" SelectedItem="{Binding ResultatSelectione, Mode=TwoWay}" BorderBrush="{x:Null}" MouseDoubleClick="lvResultat_MouseLeftDoubleClick" >
        <ListView.ItemTemplate>
            <DataTemplate DataType="viewModel:ResultatRechercheViewModel">
                <Grid Height="86" Margin="2"  >
                    <Grid.RowDefinitions>
                        <RowDefinition Height="1.5*"/>
                        <RowDefinition Height="1*"/>
                        <RowDefinition Height="1*"/>
                        <RowDefinition Height="0.5*"/>
                    </Grid.RowDefinitions>
                    <TextBlock Text="{Binding Titre}" 
                                       FontSize="20" FontWeight="Bold"  />
                    <TextBlock Text="{Binding SousTitre}" Grid.Row="1" 
                                       FontStyle="Italic" Foreground="Gray"/>
                    <TextBlock Text="{Binding Resume}" Grid.Row="2"  TextTrimming="WordEllipsis"
                                        Foreground="Gray"/>

                </Grid>
            </DataTemplate>
        </ListView.ItemTemplate>
    </ListView>

I also tried things like

<Style TargetType="ListViewItem">
    <Style.Resources>
        <!--<SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="White" />-->
        <SolidColorBrush x:Key="{x:Static SystemColors.HighlightTextBrushKey}" Color="White" />
        <SolidColorBrush x:Key="{x:Static SystemColors.ControlBrushKey}" Color="White" />
    </Style.Resources>
</Style>

EDIT 2 : I have discovered that the custom style changes the color of Textblock which have the default property as Foreground (black). If I specife Black for the color of the text of the first textblock, the text doesn't change anymore of color when the item is selected.

Please show your XAML so we can see what you mean by I have a ListView with two TextBlock in it. — Sheridan

You could achieve what you are trying to do by converting your code from having DataTemplate for a ListViewItem to having a ControlTemplate

This is what I tried:

ListViewItem Style:

<Style TargetType="ListViewItem">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type ListViewItem}">
                <Border x:Name="ContentBorder"
                                Background="{TemplateBinding Background}"
                                BorderBrush="{TemplateBinding BorderBrush}"
                                BorderThickness="{TemplateBinding BorderThickness}"
                                Margin="4">
                    <Grid Height="86" Margin="2"  >
                        <Grid.RowDefinitions>
                            <RowDefinition Height="1.5*"/>
                            <RowDefinition Height="1*"/>
                            <RowDefinition Height="1*"/>
                            <RowDefinition Height="0.5*"/>
                        </Grid.RowDefinitions>
                        <TextBlock Text="{Binding Titre}" 
                               FontSize="20" FontWeight="Bold"  />
                        <TextBlock Text="{Binding SousTitre}" Grid.Row="1" Name="st"
                               FontStyle="Italic" Foreground="Gray"/>
                        <TextBlock Text="{Binding Resume}" Grid.Row="2"  TextTrimming="WordEllipsis" Name="r"
                                Foreground="Gray"/>
                    </Grid>
                </Border>
                <ControlTemplate.Triggers>
                    <Trigger Property="IsSelected" Value="True">
                        <Setter Property="Foreground" TargetName="st" Value="White" />
                        <Setter Property="Foreground" TargetName="r" Value="White" />
                        <Setter Property="Background" TargetName="ContentBorder"  Value="DeepSkyBlue" />
                    </Trigger>
                </ControlTemplate.Triggers>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

and then I removed DataTemplate from the ListView XAML:

<ListView  x:Name="lvResultat"  Grid.Row="0" Grid.Column="1" Background="{x:Null}"  
           Margin="4"                       
           HorizontalContentAlignment="Stretch"
           ScrollViewer.VerticalScrollBarVisibility="Auto"
           ScrollViewer.HorizontalScrollBarVisibility="Disabled"
           IsSynchronizedWithCurrentItem="True"    
           ItemsSource="{Binding ResultatsRecherche}" SelectedItem="{Binding ResultatSelectione, Mode=TwoWay}" BorderBrush="{x:Null}" >
</ListView>

However, if you must use DateTemplate, then what you could do is have a property called IsSelected on your ViewModel, ResultatRechercheViewModel and then have DataTriggers on that property in your DataTemplate.

Updated DataTemplate:

<ListView.ItemTemplate>
    <DataTemplate DataType="viewModel:ResultatRechercheViewModel">
        <Grid Height="86" Margin="2"  >
            <Grid.RowDefinitions>
                <RowDefinition Height="1.5*"/>
                <RowDefinition Height="1*"/>
                <RowDefinition Height="1*"/>
                <RowDefinition Height="0.5*"/>
            </Grid.RowDefinitions>
            <TextBlock Text="{Binding Titre}" 
                           FontSize="20" FontWeight="Bold"  />
            <TextBlock Text="{Binding SousTitre}" Grid.Row="1"  Name="st"
                           FontStyle="Italic" Foreground="Gray"/>
            <TextBlock Text="{Binding Resume}" Grid.Row="2"  TextTrimming="WordEllipsis" Name="r"
                            Foreground="Gray"/>

        </Grid>
        <DataTemplate.Triggers>
            <DataTrigger Binding="{Binding IsSelected}" Value="True">
                <Setter Property="Foreground" TargetName="st" Value="White" />
                <Setter Property="Foreground" TargetName="r" Value="White" />
            </DataTrigger>
        </DataTemplate.Triggers>
    </DataTemplate>
</ListView.ItemTemplate>

And, you need to update your ViewModel code to set IsSelected property, Below is code from my MainViewModel:

public ResultatRechercheViewModel ResultatSelectione
{
    get { return _resultatSelectione; }
    set
    {
        if (_resultatSelectione != null)
        {
            _resultatSelectione.IsSelected = false;
        }

        _resultatSelectione = value;

        _resultatSelectione.IsSelected = true;
    }
}

Hope this resolves your problem or gives you some ideas to resolve your problem.
