如何在默认RadRadioButton上更改前景
我正在尝试根据RadRadioButton的默认样式来设置 RadRadioButton 的样式：

例如，假设我为 Checked 状态设置了深色背景，如何在此状态下将按钮更改为白色前景（文本颜色）？
EDIT1
基于 Chris W。的评论，我在此 CheckStates VIsualStateGroup 中添加了ColorAnimation：
<VisualStateGroup x:Name="CheckStates">
<VisualState x:Name="Checked">
<Storyboard>
<DoubleAnimation Duration="0" Storyboard.TargetName="CheckedVisual"
Storyboard.TargetProperty="Opacity" To="1" />
<ColorAnimation Storyboard.TargetName="FontColor" Storyboard.TargetProperty="Color" To="White" Duration="0:0:0" />
</Storyboard>
</VisualState>
<VisualState x:Name="Unchecked" />
</VisualStateGroup>
但这不起作用，它给了我这个错误：
EDIT2
我根据新评论对此进行了更改：
<VisualStateGroup x:Name="CheckStates">
<VisualState x:Name="Checked">
<Storyboard>
<DoubleAnimation Duration="0" Storyboard.TargetName="CheckedVisual"
Storyboard.TargetProperty="Opacity" To="1" />
<ColorAnimation Storyboard.TargetName="Content" Storyboard.TargetProperty="Foreground" To="White" Duration="0:0:0" />
</Storyboard>
</VisualState>
<VisualState x:Name="Unchecked" />
</VisualStateGroup>
但是现在我得到了这个错误：

您是否已将“检查背景”更改为“黑色？”。您可以编辑的背景属性
对于前景，请在Checked VisualState =“ Checked”内应用ColorAnimation
<VisualState x:Name="Checked">
<Storyboard>
...........
<ColorAnimation To="White" Storyboard.TargetProperty="(Control.Foreground).(SolidColorBrush.Color)" Storyboard.TargetName="Content" />
</Storyboard>
</VisualState>

注意：我无权访问telerik:RadRadioButton，因此我使用了ToggleButton作为参考
即使在Content更复杂的情况下，也可以使动画正常工作
<telerik:RadRadioButton>
<TextBlock>SomeContent</TextBlock>
</telerik:RadRadioButton>
您要设置Foreground中的RadRadioButton
通常第一种方法是这样的
<ColorAnimation To="White" Storyboard.TargetProperty="Foreground.(SolidColorBrush.Color)" Storyboard.Target="{Binding RelativeSource={RelativeSource TemplatedParent}}" />
但是您会收到此错误
System.Windows.Data错误：2：找不到目标元素的管理FrameworkElement或FrameworkContentElement ...
发生此错误是因为VisualStateManager不是VisualTree的一部分
另请参阅：WPF Error: Cannot find governing FrameworkElement for target element
要解决此问题，您必须使用BindingProxy
供参考，请参见：Binding Visibility for DataGridColumn in WPF
public class BindingProxy : Freezable
{
#region Overrides of Freezable
protected override Freezable CreateInstanceCore()
{
return new BindingProxy();
}
#endregion
public object Data
{
get { return (object)GetValue(DataProperty); }
set { SetValue(DataProperty, value); }
}
public static readonly DependencyProperty DataProperty =
DependencyProperty.Register("Data", typeof(object),
typeof(BindingProxy));
}
<ControlTemplate TargetType="{x:Type telerik:RadRadioButton}">
<Grid SnapsToDevicePixels="True">
<Grid.Resources>
<local:BindingProxy x:Key="BindingProxy" Data="{Binding RelativeSource={RelativeSource TemplatedParent}}" />
</Grid.Resources>
...
<VisualStateManager.VisualStateGroups>
<VisualStateGroup x:Name="CommonStates">
...
<VisualState x:Name="Checked">
<Storyboard>
...
<ColorAnimation To="White" Storyboard.TargetProperty="Foreground.(SolidColorBrush.Color)" Storyboard.Target="{Binding Path=Data, Source={StaticResource BindingProxy}}" />
...
</Storyboard>
</VisualState>
...
</VisualStateGroup>
...
</VisualStateManager>
...
</Grid>
</ControlTemplate>

这是应该起作用的代码（至少对我有用）：
<VisualState x:Name="Checked">
<Storyboard>
<DoubleAnimation Duration="0" To="1" Storyboard.TargetProperty="Opacity" Storyboard.TargetName="CheckedVisual"/>
<ObjectAnimationUsingKeyFrames Duration="0" Storyboard.TargetProperty="(TextElement.Foreground)" Storyboard.TargetName="Content">
<DiscreteObjectKeyFrame KeyTime="0">
<DiscreteObjectKeyFrame.Value>
<SolidColorBrush Color="White"/>
</DiscreteObjectKeyFrame.Value>
</DiscreteObjectKeyFrame>
</ObjectAnimationUsingKeyFrames>
</Storyboard>
</VisualState>
要以正确的方式制作此类样式（意味着“ Telerik推荐”），则应在设计器中的组件上单击鼠标右键->编辑模板...->编辑副本（当然，您可以在此尝试其他样式）点）。 之后，将在xaml中的Resources或App.xaml文件中生成正确的代码。有了此代码，您可以更改这些参数。希望能有所帮助。
