wpf – HighlightBrushKey设置在Windows 7中不起作用

我的资源字典中定义了以下样式：

<!-- ListViewItem Styles-->
<LinearGradientBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" StartPoint="0,0" EndPoint="0,1">
    <LinearGradientBrush.GradientStops>
        <GradientStopCollection>
            <GradientStop Color="#F7D073" Offset="0"/>
            <GradientStop Color="#F1A62F" Offset="1"/>
        </GradientStopCollection>
    </LinearGradientBrush.GradientStops>
</LinearGradientBrush>

<LinearGradientBrush x:Key="{x:Static SystemColors.ControlBrushKey}" StartPoint="0,1">
    <LinearGradientBrush.GradientStops>
        <GradientStopCollection>
            <GradientStop Color="#F7D073" Offset="0"/>
            <GradientStop Color="#F1A62F" Offset="1"/>
        </GradientStopCollection>
    </LinearGradientBrush.GradientStops>
</LinearGradientBrush>

<LinearGradientBrush x:Key="MouSEOverBrush" StartPoint="0,1">
    <LinearGradientBrush.GradientStops>
        <GradientStopCollection>
            <GradientStop Color="#E4F0FD" Offset="0"/>
            <GradientStop Color="#D7EAFD" Offset="1"/>
        </GradientStopCollection>
    </LinearGradientBrush.GradientStops>
</LinearGradientBrush>

<Style TargetType="{x:Type ListViewItem}">
    <Setter Property="Foreground" Value="{Binding RelativeSource={RelativeSource FindAncestor,AncestorType={x:Type UserControl}},Path=DataForeground,Converter={StaticResource ColorToBrushConverter}}" />
    <Setter Property="Padding" Value="1,1,0" />
    <Setter Property="FontWeight" Value="Normal" />
    <Setter Property="BorderThickness" Value="1"/>
    <Setter Property="BorderBrush" Value="Transparent"/>
    <Style.Triggers>
        <Trigger Property="IsMouSEOver" Value="true">
            <Setter Property="Background" Value="{StaticResource MouSEOverBrush}" />
            <Setter Property="BorderBrush" Value="#C6E1FC" />
            <Setter Property="BorderThickness" Value="1" />
        </Trigger>
        <Trigger Property="IsSelected" Value="True">
            <Setter Property="Foreground" Value="Black" />
            <Setter Property="BorderBrush" Value="#909090" />
            <Setter Property="BorderThickness" Value="1" />
        </Trigger>
    </Style.Triggers>
    <Style.Resources>
        <Style TargetType="Border">
            <Setter Property="CornerRadius" Value="2"/>
        </Style>
    </Style.Resources>
</Style>
<!-- /ListViewItem Styles-->

当我使用Windows XP时,我得到的行为是我的渐变用于高光和选择.现在我已经切换到使用Windows 7,似乎渐变不再使用高亮/选择颜色现在是VS外观的浅蓝色.

有关为什么会发生这种情况的任何建议,以及如何以在Windows XP和Windows 7上运行相同的方式解决此问题(我们有一个多平台环境)

谢谢.

            <Setter Property="BorderBrush" Value="#909090" />
            <Setter Property="BorderThickness" Value="1" />
        </MultiDataTrigger>
    </Style.Triggers>
    <Style.Resources>
        <Style TargetType="Border">
            <Setter Property="CornerRadius" Value="2"/>
        </Style>
    </Style.Resources>
</Style>

解决方法

Aero上的默认风格与Luna主题略有不同.在Aero中,默认样式中有一个类似的触发器：

<Trigger Property="IsSelected" Value="true">
    <Setter Property="Background" Value="{StaticResource ListItemSelectedFill}"/>
    <!-- ... -->
</Trigger>

在Luna上,它看起来像：

<Trigger Property="IsSelected" Value="true">
    <Setter TargetName="Bd" Property="Background"
        Value="{DynamicResource {x:Static SystemColors.HighlightBrushKey}}"/>
    <!-- ... -->
</Trigger>

因此,您可以看到默认的Aero风格,根本不使用HighlightBrushKey.这主要是因为这些画笔基于单一纯色.但是Aero主题有很多渐变,不能用旧式的颜色来表示.

您还需要设置Background属性以将其应用于Aero,如下所示：

<Trigger Property="IsSelected" Value="true">
    <Setter Property="Background"
        Value="{DynamicResource {x:Static SystemColors.HighlightBrushKey}}"/>
    <!-- ... -->
</Trigger>
