自定义状态按钮MVVM（Windows通用10）

Question

我希望有一个悬停效果和一个我可以在viewmodel中设置的活动状态

这就是我得到的

 <Style TargetType="Button" x:Key="btn">
    <Setter Property="Background" Value="Red"/>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate>
                <Grid>
                    <VisualStateManager.VisualStateGroups>
                        <VisualStateGroup x:Name="ApplicationViewStates">
                            <VisualState x:Name="Active">
                                <Storyboard>
                                    <ObjectAnimationUsingKeyFrames Storyboard.TargetName="Border" Storyboard.TargetProperty="Background">

                                    SelectionHighlightColor="Black"
                                    FontSize="{TemplateBinding FontSize}"

                                    VerticalAlignment="Center"
                                    Height="Auto"
                                    Width="Auto"
                                    Text="{Binding Content, RelativeSource={RelativeSource Mode=TemplatedParent}}"/>
                            </ContentPresenter>
                        </Grid>
                    </Grid>
                </Grid>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

基本上我想在任何给定时间将Visualstate设置为名为Active的那个。但是，当我悬停该项目时，悬停效果仍然需要起作用。

提前感谢。
