Question

我的按钮控件有滚动效果问题。我在点击时折叠按钮，稍后它再次变为可见，但当按钮变为可见时，鼠标悬停状态不会变回“正常”。但是，可以通过更改代码中的可视状态来解决该问题，但我想知道是否有办法在控件模板中执行此操作？这是我的模板：

<Style x:Key="replayButton" TargetType="Button">
        <Setter Property="Background" Value="#FF1F3B53"/>
        <Setter Property="Foreground" Value="#FF000000"/>
        <Setter Property="Padding" Value="3"/>
        <Setter Property="BorderThickness" Value="1"/>
        <Setter Property="BorderBrush">
            <Setter.Value>
                <LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
                    <GradientStop Color="#FFA3AEB9" Offset="0"/>
                    <GradientStop Color="#FF8399A9" Offset="0.375"/>
                    <GradientStop Color="#FF718597" Offset="0.375"/>
                    <GradientStop Color="#FF617584" Offset="1"/>
                </LinearGradientBrush>
            </Setter.Value>
        </Setter>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="Button">
                    <Grid Cursor="Hand" Height="48" Margin="0,0,0,0" Width="48">

                                    </Storyboard>
