Question

我对WPF很新，但在.NET（Winforms）方面经验丰富。我试图操纵列表框的高亮样式来控制所选项目的聚焦和未聚焦颜色。我发现的每个教程都使用自定义样式为SystemColors.HighlightBrushKey和SystemColors.ControlBrushKey分配新值。但它不起作用。在无数个小时试图让它工作之后，我想到它可能与操作系统有关。我一直在Windows 10系统上尝试它。我在Windows 7设置上运行完全相同的代码，并且看，它有效！

显然，旧的方法在Windows 10中不起作用（至少对我来说是这样的）。有人找到了替代方案吗？在一天结束时，我只想让列表框保持明亮的高光，即使它没有焦点。默认的灰色突出显示很难看到，并且在某些用法中似乎不合适。我有一个真实世界的场景，当焦点远离ListBox时，高光基本上消失的感觉非常不自然。

下面是我在Windows 7上使用的XAML代码，但在Windows 10上没有。（顺便说一下，我也尝试用SystemColors.InactiveSelectionHighlightBrushKey替换SystemColors.ControlBrushKey - 结果是一样的。）

                <!-- Background of selected item when not focused -->
                <SolidColorBrush x:Key="{x:Static SystemColors.ControlBrushKey}" Color="Green" />

微软为Windows 10打破了这个，但我们可以解决它！

这是模板在Windows 10中的样子（只是我关心的部分）：

[Stime, Etime)

请注意，他们对颜色的值进行了硬编码，例如＆＃34;＃1F26A0DA＆＃34;。

在Windows 7中，ListBoxItems的内置模板是：

   <ControlTemplate TargetType="{x:Type ListBoxItem}">
 ...
        <Border x:Name="Bd" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" Padding="{TemplateBinding Padding}" SnapsToDevicePixels="True">
            <ContentPresenter ContentTemplate="{TemplateBinding ContentTemplate}" Content="{TemplateBinding Content}" ContentStringFormat="{TemplateBinding ContentStringFormat}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
        </Border>
        <ControlTemplate.Triggers>
            <MultiTrigger>
                <MultiTrigger.Conditions>
                    <Condition Property="IsMouseOver" Value="True"/>
                </MultiTrigger.Conditions>
                <Setter Property="Background" TargetName="Bd" Value="#1F26A0DA"/>
                <Setter Property="BorderBrush" TargetName="Bd" Value="#A826A0DA"/>
            </MultiTrigger>
            <MultiTrigger>
                <MultiTrigger.Conditions>
                    <Condition Property="Selector.IsSelectionActive" Value="False"/>
                    <Condition Property="IsSelected" Value="True"/>
                </MultiTrigger.Conditions>
                <Setter Property="Background" TargetName="Bd" Value="#3DDADADA"/>
                <Setter Property="BorderBrush" TargetName="Bd" Value="#FFDADADA"/>
            </MultiTrigger>
            <MultiTrigger>
                <MultiTrigger.Conditions>
                    <Condition Property="Selector.IsSelectionActive" Value="True"/>
                    <Condition Property="IsSelected" Value="True"/>
                </MultiTrigger.Conditions>
                <Setter Property="Background" TargetName="Bd" Value="#3D26A0DA"/>
                <Setter Property="BorderBrush" TargetName="Bd" Value="#FF26A0DA"/>
            </MultiTrigger>
            <Trigger Property="IsEnabled" Value="False">
                <Setter Property="TextElement.Foreground" TargetName="Bd" Value="{DynamicResource {x:Static SystemColors.GrayTextBrushKey}}"/>
            </Trigger>
        </ControlTemplate.Triggers>
    </ControlTemplate>

因此，基本上微软使用的资源类似于＆＃34; SystemColors.InactiveSelectionHighlightBrushKey＆＃34;在Windows 7中。但是现在他们已经做到了，所以我们无法覆盖模板而无法做到这一点;因为他们硬编码了所有的值。

为了修补此问题，只需在App.Xaml文件中覆盖ListBoxItem的模板;所以一切都得到补丁。

         <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="{DynamicResource {x:Static SystemColors.HighlightBrushKey}}"/>
                            <Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.HighlightTextBrushKey}}"/>
                        </Trigger>
                        <MultiTrigger>
                            <MultiTrigger.Conditions>
                                <Condition Property="IsSelected" Value="true"/>
                                <Condition Property="Selector.IsSelectionActive" Value="false"/>
                            </MultiTrigger.Conditions>
                            <Setter Property="Background" TargetName="Bd" Value="{DynamicResource {x:Static SystemColors.InactiveSelectionHighlightBrushKey}}"/>
                            <Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.InactiveSelectionHighlightTextBrushKey}}"/>
                        </MultiTrigger>
                        <Trigger Property="IsEnabled" Value="false">
                            <Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.GrayTextBrushKey}}"/>
                        </Trigger>
                    </ControlTemplate.Triggers>
          </ControlTemplate>

如果您确实要更改应用的默认设置，则可以随时通过制作模板副本来修改样式。在这种情况下为ListBoxItem样式。

在设计器中，单击ListBoxItem，右键单击“编辑模板”，然后单击“编辑副本”。

以下是我在我的机器上获得的内容，以及使用Red / Green运行的应用程序的屏幕截图，演示了应用于受影响项目的样式。你当然会将它应用于所有项目......

Answer 3

我在Windows 10下的ListBoxes的突出显示样式有类似的问题...旧的SystemColors.HighlightBrushKey和SystemColors.ControlBrushKey解决方案在Windows 7下仅适用于我。在我的情况下，我只是想删除任何WPF绘制的突出显示，所以我可以用我自己的替换它。

为此，我只是通过我的资源中的以下简短样式替换了ControlTemplate：

        <Style TargetType="{x:Type ListBoxItem}">
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="{x:Type ListBoxItem}">
                        <ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>

我一般不喜欢更换详细的ControlTemplates，但这对我来说是一个很好的简洁解决方案，希望它可以帮助其他人。

Answer 4

我担心我没有办法在Windows 10中专门测试这个，但是我在Windows 7上遇到了类似的问题。在参考资料中定义“ControlBrushKey”并不起作用。< / p>

设置“InactiveSelectionHighlightBrushKey”对我有用：

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

道奇蓝与默认的Aero选择非常接近;它只是一个头发更黑。我还在努力弄清楚如何将它映射到实际的选择值而不是特定的颜色。
