有人可以向我展示如何在Silverlight XAML中设置样式的单选按钮以使其聚焦时（或更改其颜色）吗？

Question

I have a radiobutton VisualStateGroup for Focuses, but I don't know how to change the storyboard to highlight the radiobutton on focus.

 <VisualStateGroup x:Name="FocusStates">
                                    <VisualState x:Name="Focused">
                                        <Storyboard>
                                            <DoubleAnimationUsingKeyFrames Storyboard.TargetName="ContentFocusVisualElement" Storyboard.TargetProperty="Opacity">
                                                <SplineDoubleKeyFrame KeyTime="0" Value="1"/>
                                            </DoubleAnimationUsingKeyFrames>
                                        </Storyboard>
                                    </VisualState>
                                    <VisualState x:Name="Unfocused"/>
                                </VisualStateGroup>

I worked it out. It turns out the the target element needed to be layered on top of the other elements.
