【问题描述】：

我的资源字典中定义了以下样式：

<!-- ListViewItem Styles-->

    <LinearGradientBrush.GradientStops>
        <GradientStopCollection>
            <GradientStop Color="#F7D073" Offset="0"/>
            <GradientStop Color="#F1A62F" Offset="1"/>

        </GradientStopCollection>
    </LinearGradientBrush.GradientStops>
</LinearGradientBrush>

        <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被用于高亮和选择。现在我已经切换到使用 Windows 7，似乎不再使用渐变，突出显示/选择颜色现在是 VS 外观的浅蓝色。

关于为什么会发生这种情况以及如何解决这个问题的任何建议，以便它在 Windows XP 和 Windows 7 上运行相同（我们有一个多平台环境）

谢谢。

【参考方案1】：

Aero 上的默认样式与 Luna 主题有些不同。在 Aero 中，默认样式中有一个类似这样的触发器：

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

在 Luna 上时，它看起来像：

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

所以你可以看到 Aero 的默认样式，根本不使用 HighlightBrushKey。这主要是因为这些画笔基于单一的纯色。但是 Aero 主题有很多渐变色，这是旧款颜色无法表现的。

您还需要设置 Background 属性才能将其应用于 Aero，如下所示：

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

这正是我所需要的。你的评论帮助我朝着正确的方向前进。我已将完整的 Aero 解决方案添加到我原来的问题中。谢谢
