我想，这是一个bug。

要复制，在Windows Phone上启动深色主题的应用程序。应用程序启动后，将主题更改为light。然后点击"启用"按钮。您将看到"样本"按钮消失。因为它的主题仍然是黑暗。

<Page x:Class="ButtonThemeTest.MainPage"
      xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
      xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
      xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
      xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
      Background="{ThemeResource ApplicationPageBackgroundThemeBrush}"
      mc:Ignorable="d">
    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition Height="Auto" />
            <RowDefinition Height="Auto" />
            <RowDefinition Height="Auto" />
        </Grid.RowDefinitions>
        <Button x:Name="ButtonTest"
                Content="Sample"
                IsEnabled="False" />
        <Button Grid.Row="1"
                Click="ButtonBase_OnClick"
                Content="Enable" />
        <Button Grid.Row="2"
                Click="ButtonBase_OnClick2"
                Content="Disable" />
    </Grid>
</Page>

背后的代码:

private void ButtonBase_OnClick(object sender, RoutedEventArgs e)
{
    ButtonTest.IsEnabled = true;
}
private void ButtonBase_OnClick2(object sender, RoutedEventArgs e)
{
    ButtonTest.IsEnabled = false;
}

更改主题不会影响Windows Phone 8.1上已禁用的控制主题

我找到的唯一解决方案是从通用中获得按钮样式。并在Normal视觉状态中添加storyboard，如下所示:

<Storyboard>
    <ObjectAnimationUsingKeyFrames Storyboard.TargetName="ContentPresenter"
                                   Storyboard.TargetProperty="Foreground">
        <DiscreteObjectKeyFrame KeyTime="0"
                                Value="{ThemeResource PhoneForegroundBrush}" />
    </ObjectAnimationUsingKeyFrames>
    <ObjectAnimationUsingKeyFrames Storyboard.TargetName="Border"
                                   Storyboard.TargetProperty="BorderBrush">
        <DiscreteObjectKeyFrame KeyTime="0"
                                Value="{ThemeResource PhoneForegroundBrush}" />
    </ObjectAnimationUsingKeyFrames>
    <ObjectAnimationUsingKeyFrames Storyboard.TargetName="Border"
                                   Storyboard.TargetProperty="Background">
        <DiscreteObjectKeyFrame KeyTime="0"
                                Value="{ThemeResource PhoneBackgroundBrush}" />
    </ObjectAnimationUsingKeyFrames>
</Storyboard>

使用Visual studio Blend为按钮设置样式
