我有有史以来最简单的应用程序:带有一个切换按钮的单个窗口:

<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">
    <Grid>
        <ToggleButton Content="This is my ToggleButton" />
    </Grid>
</Window>

当我现在单击切换按钮时,实际上什么都没有发生。当我为CheckedUnchecked事件设置事件处理程序,然后单击按钮时,首先Checked然后Unchecked被触发。所以按钮似乎工作正常......

我正在编译为 .NET 4.5,并且正在使用 Windows 8 RTM。

此行为是否与 Windows 8 显示按钮的样式(无“3D”边框)有关?任何人都可以确认吗?

更新 1 我制作了一张图片来说明我的意思:

Windows 8 与 Windows 7 切换按钮

如您所见,在 Windows 8 中,单击切换按钮时“没有任何反应”,它根本不会“切换”。这似乎是一个错误,与 Windows 8 显示按钮的样式有关......

更新:2013 年 5 月 30 日: 有一个修补程序:http: //support.microsoft.com/kb/2805222
请参阅 WPF 下的问题 #5
不幸的是,它并不能解决我的问题 :(

这是 WPF 中已确认的缺陷。解决方法是相应地设置控件的样式,尽管产品组可能会考虑修复。要请求修复,请联系 Microsoft 支持。

对于想要一些代码开始的每个人,您可以使用我用来设置控件样式的代码:

<Application.Resources>

        <!-- Toogle button fix (includes custom button + toggle button style) -->
        <Style TargetType="{x:Type Button}">
            <Setter Property="Background" Value="{StaticResource ButtonNormalBackground}"/>
            <Setter Property="BorderBrush" Value="{StaticResource ButtonNormalBorder}"/>
            <Setter Property="BorderThickness" Value="1"/>
            <Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}"/>
            <Setter Property="HorizontalContentAlignment" Value="Center"/>
            <Setter Property="VerticalContentAlignment" Value="Center"/>
            <Setter Property="Padding" Value="1"/>
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="{x:Type Button}">
                        <Border BorderThickness="1" BorderBrush="#FFA4A4A4">
                            <Grid>
                                <Rectangle x:Name="Rectangle_Background" Fill="#FFEDEDED" />
                                <ContentPresenter x:Name="ContentPresenter_Content" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" RecognizesAccessKey="True" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
                            </Grid>
                        </Border>
                        <ControlTemplate.Triggers>
