wpf 如何禁用列表框上的突出显示但保持选择？

How to disable highlighting on listbox but keep selection?

提问by Aero Chocolate

I am having trouble finding how to not allow my ListBox to highlight the item selected. I know that I didn't add a trigger to highlight the item.

我无法找到如何不允许我的 ListBox 突出显示所选项目。我知道我没有添加触发器来突出显示该项目。

<ListBox Name="CartItems" ItemsSource="{Binding}"
         ItemTemplate="{StaticResource TicketTemplate}" 
         Grid.Row="3" Grid.ColumnSpan="9" Background="Transparent"
         BorderBrush="Transparent">
</ListBox>

        <ListBox.ItemContainerStyle>
            <Style TargetType="ListBoxItem">
                <Setter Property="IsSelected" Value="{Binding Content.IsSelected, Mode=TwoWay, RelativeSource={RelativeSource Self}}"/>
                <Setter Property="Template">
                    <Setter.Value>
                        <ControlTemplate TargetType="ListBoxItem">
                            <ContentPresenter/>
                        </ControlTemplate>
                    </Setter.Value>

            </Style>
        </ListBox.ItemContainerStyle>

Late answer, but there's a much better and simpler solution:

迟到的答案，但有一个更好、更简单的解决方案：

<ListBox>
   <ListBox.Resources>
      <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Transparent" />
      <SolidColorBrush x:Key="{x:Static SystemColors.HighlightTextBrushKey}" Color="Black" />
      <SolidColorBrush x:Key="{x:Static SystemColors.ControlBrushKey}" Color="Transparent" />  
   </ListBox.Resources>
</ListBox>

This allows you to have a LisBox that looks just like an itemscontrol, but has support for selection.

这允许您拥有一个看起来就像一个项目控件但支持选择的 LisBox。

Edit:Howit works
This alters "colors of the system", in other words your windows theme, only for this ListBox and its children (we actually want to target the ListboxItem).

编辑：它是如何工作的
这会改变“系统的颜色”，换句话说就是你的 Windows 主题，只针对这个 ListBox 及其子项（我们实际上想要针对ListboxItem）。

For example hovering a ListboxItemusually gives it a deep blue background, but here we set it to transparent (HighlightBrushKey).

例如，悬停 aListboxItem通常会给它一个深蓝色背景，但在这里我们将它设置为透明 (HighlightBrushKey)。

Edit (30 June 2016):
It seems for latest Windows version this is not enough anymore, you also need to redefine InactiveSelectionHighlightBrushKey

编辑（2016 年 6 月 30 日）：
对于最新的 Windows 版本，这似乎还不够，您还需要重新定义InactiveSelectionHighlightBrushKey

<SolidColorBrush x:Key="{x:Static SystemColors.InactiveSelectionHighlightBrushKey}" Color="Transparent" />

removing the highlighting completely feels very odd, as you dont know if you've selected anything, but here's a version of the control template that uses WhiteSmoke(which is very subtle) instead of Blue

完全删除突出显示感觉很奇怪，因为你不知道你是否选择了任何东西，但这里有一个控制模板的版本，它使用WhiteSmoke（非常微妙）而不是Blue

<Window.Resources>
    <Style x:Key="ListBoxItemStyle1" TargetType="{x:Type ListBoxItem}">
        <Setter Property="Background" Value="Transparent"/>
        <Setter Property="HorizontalContentAlignment" Value="{Binding HorizontalContentAlignment, 
            RelativeSource={RelativeSource AncestorType={x:Type ItemsControl}}}"/>
        <Setter Property="VerticalContentAlignment" Value="{Binding VerticalContentAlignment,
             RelativeSource={RelativeSource AncestorType={x:Type ItemsControl}}}"/>
        <Setter Property="Padding" Value="2,0,0,0"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type ListBoxItem}">
                    <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>
                        <Trigger Property="IsSelected" Value="true">
                            <Setter Property="Background" TargetName="Bd" Value="WhiteSmoke"/>
                        </Trigger>
                    </ControlTemplate.Triggers>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
</Window.Resources>

<Grid x:Name="LayoutRoot">
    <ListBox HorizontalAlignment="Left" VerticalAlignment="Top" ItemContainerStyle="{DynamicResource ListBoxItemStyle1}">
        <ListBoxItem Content="Item1"/>
        <ListBoxItem Content="Item2"/>
        <ListBoxItem Content="Item3"/>
        <ListBoxItem Content="Item4"/>
        <ListBoxItem Content="Item5"/>
        <ListBoxItem Content="Item6"/>
    </ListBox>
</Grid>

here's what worked for me.

这对我有用。

<Style x:Key="ListBoxNoHighlight" TargetType="ListBoxItem">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="ListBoxItem">
                    <Border Background="{TemplateBinding Background}">

In the Properties tab, there is an Enabled Field with 2 options, true and false. By turning this to false, the Listbox remains white and selection is not avaliable. Just figured this out!

在 Properties 选项卡中，有一个 Enabled Field，有 2 个选项，true 和 false。通过将此设置为 false，列表框保持白色并且选择不可用。刚刚想通了这一点！

I'm talking about a trick I did in my WP8 app.

我说的是我在我的 WP8 应用程序中做的一个技巧。

I added a transparent frame image above it (the image's border was seen, think of it like a picture frame). The scroll was functional, any manipulation event was firing just that the Listbox items weren't selected anylonger.

我在它上面添加了一个透明的框架图像（可以看到图像的边框，把它想象成一个相框）。滚动是有效的，任何操作事件都会触发，只是不再选择列表框项目。

<Grid 
        Grid.Row="0" 
        Margin="10,15"
        Background="#FF008F88">
        <ListBox 
            x:Name="listBox_content" 
            Margin="20,15"
            VirtualizingStackPanel.VirtualizationMode="Recycling">
        </ListBox>

        <!-- TV image, middle is transparent so the ListBox can be seen -->
        <Image 
                x:Name="image_tv" 
                Source="/Assets/Images/tvFrame.png" 
                Stretch="Fill"/>
        <!---->
    </Grid>

I guess this could work with a full transparent image set to Fill as well.

我想这也可以与设置为 Fill 的完全透明图像一起使用。

You will have to re-template ListBoxItem. In the default template, it has a trigger that highlights itself when IsSelectedproperty is true. You just have to create a template that does not have that trigger.

您将不得不重新模板ListBoxItem。在默认模板中，它有一个触发器，当IsSelected属性为true. 您只需要创建一个没有该触发器的模板。
