為什么單選按鈕沒有出現在Windows 8的彈出窗口中？

Question

我已經使用VS2010在Windows 7上開發了WPF / C＃/。NET 4.0應用程序。 該應用程序可以很好地運行，並且可以在XP和Windows 7上正常運行。但是，在具有最新更新的Windows 8上，單選按鈕（默認選擇的按鈕除外）不會顯示在彈出窗口中，盡管有空格。 如果將鼠標移到單選按鈕應位於的位置，則當鼠標懸停在單選按鈕上時，該按鈕將按原樣顯示。 然后，將鼠標從其上方移開時，該按鈕將按原樣顯示，而當鼠標不在其上方時，該按鈕應以開始但沒有的方式顯示。

在我有單選按鈕的所有其他情況下，它們都按應有的方式工作，除了它們沒有按應有的對齊方式。 它們在XP和Windows 7中正確對齊。

更正：我使用.NET 3.5開發了它，最近又更改為.NET 4.0平台。 在.NET 3.5平台上編譯並在Windows 8上運行時，這些單選按鈕將按應有的方式顯示。 除了切換到.NET 4.0平台並進行編譯，然后在Windows 8下運行外，無需進行其他任何更改，單選按鈕不再顯示應有的樣子，而是將鼠標移到它們上方時應有的樣子。

第一次顯示彈出窗口時，如何使那些單選按鈕顯示在非鼠標懸停狀態？

這是彈出的XAML，所有其他控件在Windows 8中都可以正常顯示和運行，例如CheckBoxes：

<Popup Name="MainPrintMenu"
        PlacementTarget="{Binding ElementName=btnPrint}"
        Placement="Bottom"
        HorizontalOffset="-99"
        VerticalOffset="-5"
        AllowsTransparency="True"
        StaysOpen="False">
    <Border BorderThickness="2"
            Background="White"
            CornerRadius="5"
            BorderBrush="Black">
        <Grid Background="Transparent">
            <StackPanel Name="PrintButtons"

                        Margin="5"
                        >
                <StackPanel.Resources>

Answer 1

事實證明這很容易解決。 這是上述問題的XAML部分已更改：

<Style TargetType="RadioButton">
    <Setter Property="FontSize" Value="10" />
    <Setter Property="FontWeight" Value="Bold" />
    <Setter Property="HorizontalContentAlignment" Value="Left" />
    <Setter Property="BorderBrush" Value="{x:Null}" />
    <Style.Triggers>
        <Trigger Property="IsEnabled" Value="False">
            <Setter Property="Opacity" Value="0.50" />
        </Trigger>
    </Style.Triggers>
</Style>

需要做的就是從上述XAML中刪除以下行：

<Setter Property="BorderBrush" Value="{x:Null}" />

用於設置RadioButton樣式的XAML來自此處的另一篇文章，但是Values更改為我需要的內容。 我已經離開了BorderBrush值。
