我正在用 C# 编写一个 Windows 8 WinRT 应用程序，并希望动态更改我的ToggleSwitch. 我将有这些实例的多个实例，它们不会都有相同的颜色。
我尝试创建一个继承自 的自定义控件ToggleSwitch，但我很快了解到我不能这样做，因为ToggleSwitch它是一个sealed类。我的目标是添加一个DependencyPropertytype Brush，然后TemplateBinding在我的自定义控件的Template.
有没有另一种方法可以做到这一点？
您将能够在 Blend 中进行操作
右键单击 ToggleSwitch > 编辑模板 > 编辑副本
Blend 将在<Page.Resource>. 更改Storyboard.TargetName="SwitchCurtain属性将更改窗帘的颜色。

对于它的价值，我最近在寻找同样的东西并找到了这个 MS 链接。只需将颜色更改为您不需要样式的颜色，除非您真的必须降到那么低。

你有没有尝试过这样的事情是不是不起作用
toggleSwitch.toggle.SwitchForeground = new SolidColorBrush(Colors.Green)
阅读有关您的问题的更多信息，您可以完全切换，但您必须为切换创建多种样式并应用您想要的样式
toggleSwitch.Style = this.FindResource("toggleSwitchsTYLE") as Style;
http://www.windowsphonegeek.com/articles/wp7-toggleswitch-in-depth--key-concepts-and-api
我决定在自定义样式中重新使用 Background 属性，其中分配给 Background 属性的值将模板绑定到 SwitchCurtain 的 Fill。由于无论如何我都不会使用 Background 属性的实际用途，因此这似乎是理想的方法。
<ResourceDictionary.ThemeDictionaries>
<ResourceDictionary x:Key="Default">
<SolidColorBrush x:Key="ToggleSwitchFillOn" Color="Red"/>
</ResourceDictionary>
</ResourceDictionary.ThemeDictionaries>
将上面的代码添加到您的 App.xaml
