WPF ListView Inactive Selection Color
提问by Joseph Sturtevant
I'm creating a WPF application where several ListView selections are made in a row (similar to the iTunes browser). The problem is that the default inactive selection color is too light. (see below)
我正在创建一个 WPF 应用程序，其中连续进行了多个 ListView 选择（类似于 iTunes 浏览器）。问题是默认的非活动选择颜色太浅了。（见下文）
How can I change this color so my inactive listview looks like this? (see below)
如何更改此颜色以使我的非活动列表视图看起来像这样？（见下文）
Solution
解决方案
Override the default SystemColor with a Stylelike so:
Style像这样覆盖默认的 SystemColor ：
<Style TargetType="ListViewItem">
<Style.Resources>
<SolidColorBrush x:Key="{x:Static SystemColors.ControlBrushKey}" Color="{x:Static SystemColors.HighlightColor}"/>
</Style.Resources>
</Style>

The ListBoxtemplate uses a system color called ControlBrushto set the inactive highlight color. Therefore, you can just override that color:
该ListBox模板使用称为系统颜色ControlBrush来设置非活动突出显示颜色。因此，您可以覆盖该颜色：
<ListBox>
<ListBox.Resources>
<SolidColorBrush x:Key="{x:Static SystemColors.ControlBrushKey}">Red</SolidColorBrush>
</ListBox.Resources>
</ListBox>

Changing SystemColors.ControlBrushKeydid not work for me, I had to change
SystemColors.InactiveSelectionHighlightBrushKey
改变SystemColors.ControlBrushKey对我不起作用，我必须改变
SystemColors.InactiveSelectionHighlightBrushKey
So instead of:
所以而不是：
<SolidColorBrush x:Key="{x:Static SystemColors.ControlBrushKey}" Color="Red" />
I had to use:
我不得不使用：
<SolidColorBrush x:Key="{x:Static SystemColors.InactiveSelectionHighlightBrushKey}" Color="Red"/>

The answer will in some cases solve the problem, but is not ideal as it breaks when the control is disabled/readonly and it also overrides the color schemes, rather than taking advantage of them. My suggestion is to add the following in the ListBox tags instead:
在某些情况下，答案将解决问题，但并不理想，因为当控件被禁用/只读时它会中断，并且它还会覆盖配色方案，而不是利用它们。我的建议是在 ListBox 标签中添加以下内容：
<ListBox....>
<ListBox.Resources>
<Style TargetType="ListBoxItem">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ListBoxItem">
<Border Name="Border" Padding="2" SnapsToDevicePixels="true">
<ContentPresenter />
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsSelected" Value="true">
<Setter TargetName="Border" Property="Background"
Value="{DynamicResource {x:Static SystemColors.HighlightBrushKey}}"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</ListBox.Resources>
</ListBox>
What this will do is set the Highlight background color on the list box item whenever it is selected (regardless of the control state).
这将做的是在列表框项目被选中时（无论控件状态如何）设置突出显示背景颜色。

You have to override some properties of SystemColors. Take a look at SystemColors Class (MSDN). There are more properties than InactiveSelectionHighlightBrushKey, e.g. InactiveSelectionHighlightTextBrushKey which affects the color of text.
您必须覆盖 SystemColors 的某些属性。看看SystemColors Class (MSDN)。有比 InactiveSelectionHighlightBrushKey 更多的属性，例如影响文本颜色的 InactiveSelectionHighlightTextBrushKey。
<Window x:Class="WpfApplication1.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525">
<Window.Resources>
<SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Red"/>
<SolidColorBrush x:Key="{x:Static SystemColors.HighlightTextBrushKey}" Color="White"/>
<SolidColorBrush x:Key="{x:Static SystemColors.InactiveSelectionHighlightBrushKey}" Color="Yellow"/>
<SolidColorBrush x:Key="{x:Static SystemColors.InactiveSelectionHighlightTextBrushKey}" Color="Blue"/>
<Style TargetType="ListViewItem">
<Setter Property="FontSize" Value="20" />
<Setter Property="FontWeight" Value="Bold" />
<Setter Property="Padding" Value="25,5" />
</Style>
</Window.Resources>
<StackPanel Orientation="Horizontal">
<ListView>
<ListViewItem Content="Item" />
<ListViewItem Content="Item" />
</ListView>
<ListView>
<ListViewItem Content="Item" />
<ListViewItem Content="Item" />
</ListView>
</StackPanel>
</Window>

Based on this other answerI used the following to make the active & inactive colors the same without hardcoding the actual value:
基于这个其他答案，我使用以下内容使活动和非活动颜色相同，而无需对实际值进行硬编码：
<ListBox.Resources>
<SolidColorBrush x:Key="{x:Static SystemColors.InactiveSelectionHighlightBrushKey}"
Color="{x:Static SystemColors.HighlightColor}"/>
<SolidColorBrush x:Key="{x:Static SystemColors.InactiveSelectionHighlightTextBrushKey}"
Color="{x:Static SystemColors.HighlightTextColor}"/>
</ListBox.Resources>
Having the same colors for both active & inactive may not be ideal, but the default colors were so faint it was hard to tell which item was selected when it was inactive; this is a definite improvement.
活动和非活动的颜色相同可能并不理想，但默认颜色太暗了，很难分辨哪个项目是非活动时被选中的；这是一个明确的改进。

In older .NET Frameworks overriding system colors does't work. Solution that works in .NET Framework 4.0 is here.
在较旧的 .NET Framework 中，覆盖系统颜色不起作用。适用于 .NET Framework 4.0 的解决方案在这里。
<ListView>
<ListView.Resources>
<Style TargetType="{x:Type ListViewItem}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ListViewItem}">
<Border x:Name="Bd"
BorderBrush="{TemplateBinding BorderBrush}"
BorderThickness="{TemplateBinding BorderThickness}"
Background="{TemplateBinding Background}"
Padding="{TemplateBinding Padding}"
SnapsToDevicePixels="true">
<ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"
SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"
VerticalAlignment="{TemplateBinding VerticalContentAlignment}" />
</Border>
<ControlTemplate.Triggers>
<MultiTrigger>
<MultiTrigger.Conditions>
<Condition Property="Selector.IsSelectionActive"
Value="False" />
<Condition Property="IsSelected"
Value="True" />
</MultiTrigger.Conditions>
<Setter Property="Background"
TargetName="Bd"
Value="DarkOrange" />
</MultiTrigger>
<MultiTrigger>
<MultiTrigger.Conditions>
<Condition Property="Selector.IsSelectionActive"
Value="True" />
<Condition Property="IsSelected"
Value="True" />
</MultiTrigger.Conditions>
<Setter Property="Background"
TargetName="Bd"
Value="OrangeRed" />
</MultiTrigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Works both for ListBox and ListView.
适用于 ListBox 和 ListView。

For me this did the trick:
对我来说，这成功了：
<ListBox HorizontalContentAlignment="Stretch">
<ListBox.ItemTemplate>
<DataTemplate>
<Label Margin="-5, -2,-5,-2" Content="{Binding Item}">
<Label.Style>
<Style TargetType="Label">
<Style.Triggers>
<MultiDataTrigger>
<MultiDataTrigger.Conditions>
<Condition Binding="{Binding RelativeSource={RelativeSource Mode=FindAncestor,AncestorType={x:Type ListBox}},Path=IsFocused}" Value="False"/>
<Condition Binding="{Binding RelativeSource={RelativeSource Mode=FindAncestor,AncestorType={x:Type ListBoxItem}},Path=IsSelected}" Value="True"/>
</MultiDataTrigger.Conditions>
<Setter Property="Background" Value="CornflowerBlue"/>
</MultiDataTrigger>
<DataTrigger Binding="{Binding RelativeSource={RelativeSource Mode=FindAncestor,AncestorType={x:Type ListBoxItem}},Path=IsSelected}" Value="True">
<Setter Property="Foreground" Value="White"/>
</DataTrigger>
<DataTrigger Binding="{Binding RelativeSource={RelativeSource Mode=FindAncestor,AncestorType={x:Type ListBoxItem}},Path=IsSelected}" Value="False">
<Setter Property="Foreground" Value="Black"/>
</DataTrigger>
</Style.Triggers>
</Style>
</Label.Style>
</Label>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
