我想知道是否有人找到了解决这个问题的方法。将TimePicker控件设置为IsEnabled属性为false会正确显示时间图标，但主时间显示根本不显示。两个合成控件确实被禁用，因为点击它们都不响应鼠标点击它只是主时间显示的视觉表示不重影。有没有人成功找到解决方法呢？
感谢。

这可以在不通过编辑混合中的TimeUpDownStyle模板来对控件进行子类化的情况下完成。该模板具有禁用的可视状态，您可以使用它将上/下区域的整个网格的不透明度设置为35％。
我在这里添加XAML以供参考，但请注意，与原始模板的唯一区别是为顶级网格指定名称<Grid x:Name="grid">，然后在禁用的可视状态下更改其不透明度：
<VisualState x:Name="Disabled">
<Storyboard>
<DoubleAnimationUsingKeyFrames BeginTime="00:00:00" Duration="00:00:00.0010000" Storyboard.TargetName="grid" Storyboard.TargetProperty="(UIElement.Opacity)">
<EasingDoubleKeyFrame KeyTime="00:00:00" Value="0.35"/>
</DoubleAnimationUsingKeyFrames>
</Storyboard>
</VisualState>
只需在Blend中点击几下即可轻松完成所有操作。
