具有结果数据触发情节提要和鼠标悬停背景的WPF按钮

Question

我正在寻求实现此功能：绑定到命令的按钮，可以以红色或绿色闪烁的形式向后发信号通知命令是否成功。 同时，我希望该按钮看起来像其他按钮。

这是我现在拥有的代码：

 <Button IsEnabled="{Binding EmptyingAllowed}" Content="Töm lista" Foreground="#555555" FontWeight="SemiBold" Height="20" Width="65" Command="{Binding EmptyListCommand}" >
        <Button.Style>
            <Style TargetType="Button">
                <Setter Property="Template">
                    <Setter.Value>
                        <ControlTemplate TargetType="Button">
                            <Border BorderBrush="#BBBBBB" Padding="1" BorderThickness="0,0,1,1" Background="#DDDDDD">
                                    <Grid Background="{TemplateBinding Background}">
                                        <ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center" />
                                    </Grid>
                                </Border>
                            </ControlTemplate>
                        </Setter.Value>
                    </Setter>
                    <Style.Triggers>
                        <DataTrigger Binding="{Binding ClearedOk}" Value="Ok">
                            <DataTrigger.EnterActions>
                                <BeginStoryboard>
                                    <Storyboard>
                                        <ColorAnimation AccelerationRatio="0.2" DecelerationRatio="0.01" AutoReverse="True" Duration="0:0:1" To="LawnGreen" Storyboard.TargetProperty="(Button.Background).(SolidColorBrush.Color)"/>
                                    </Storyboard>
                                </BeginStoryboard>
                            </DataTrigger.EnterActions>
                        </DataTrigger>
                        <DataTrigger Binding="{Binding ClearedOk}" Value="Error">
                            <DataTrigger.EnterActions>
                                <BeginStoryboard>
                                    <Storyboard>
                                        <ColorAnimation  AccelerationRatio="0.2" DecelerationRatio="0.01" AutoReverse="True" Duration="0:0:1" To="Red" Storyboard.TargetProperty="(Button.Background).(SolidColorBrush.Color)"/>
                                    </Storyboard>
                                </BeginStoryboard>
                            </DataTrigger.EnterActions>
                        </DataTrigger>
                    </Style.Triggers>
                </Style>
            </Button.Style>
        </Button>

执行命令时，将ClearedOk设置为“ Ok”或“ Error”，然后设置为“ Empty”，这会导致我正在寻找的闪存，不幸的是，由于某些原因，失去了通常的mouseOver-effect，如果我添加mouseOver-trigger，它始终优先于闪烁效果，这意味着仅按钮可见的闪烁不是mouseOver：ed。

有针对这个的解决方法吗？

尝试使数据模板和模型具有状态属性，然后将模板绑定到该属性。

 <DataTemplate x:Key="DataTemplate">
        <Grid >
            <Ellipse Stroke="White"
                     StrokeThickness="5"
                     Fill="{Binding State, Converter={StaticResource CheckToColorConverter}}"/>
        </Grid>
    </DataTemplate>
