WPF ListView Highlight Color don't change
提问by Pak
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.
我有一个 ListView，每个项目都有三个 TextBlock。第一个具有默认颜色（黑色），其他的将属性 Foreground 设置为灰色。
When I select an item the color of the first TextBlock becomes blue but the others stay gray and are hard to read.
当我选择一个项目时，第一个 TextBlock 的颜色变为蓝色，但其他保持灰色且难以阅读。
I want that all the text become white color when the item is selected. How I do that ?
我希望在选择项目时所有文本都变成白色。我怎么做？
Edit : My style :
编辑：我的风格：
<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
我的列表视图
<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
我也尝试过类似的事情
<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.
编辑 2：我发现自定义样式会更改 Textblock 的颜色，其默认属性为前景（黑色）。如果我将第一个文本块的文本颜色指定为黑色，则选择该项目时文本不再更改颜色。

You could achieve what you are trying to do by converting your code from having DataTemplatefor a ListViewItemto having a ControlTemplate
您可以通过将代码从 has DataTemplatefor a转换为 has aListViewItem来实现您想要做的事情ControlTemplate
This is what I tried:
这是我尝试过的：
ListViewItem Style:
列表视图项样式：
<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 ListViewXAML:
然后我从ListViewXAML 中删除了 DataTemplate ：
<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 IsSelectedon your ViewModel, ResultatRechercheViewModeland then have DataTriggers on that property in your DataTemplate.
但是，如果您必须使用DateTemplate，那么您可以做的是IsSelected在您的 上调用一个属性ViewModel，ResultatRechercheViewModel然后在您的DataTemplate.
Updated DataTemplate:
更新的数据模板：
<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 ViewModelcode to set IsSelectedproperty, Below is code from my MainViewModel:
而且，您需要更新ViewModel代码以设置IsSelected属性，以下是我的 MainViewModel 中的代码：
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.
希望这能解决您的问题或为您提供一些解决问题的想法。
