我們可以爲WPF XAML中的多個按鈕創建單個Storyboard嗎？

Question

<Window.Resources> 
     <Storyboard x:Key="ButtonEffect_01" AutoReverse="True" RepeatBehavior="Forever"> 
      <ColorAnimationUsingKeyFrames 
        Storyboard.TargetProperty="(UIElement.Effect).(DropShadowEffect.Color)" 
        Storyboard.TargetName="btnAdd"> 
       <EasingColorKeyFrame KeyTime="0" Value="Black"/> 
       <EasingColorKeyFrame KeyTime="0:0:0.4" Value="#FFF3FF00"/> 
      </ColorAnimationUsingKeyFrames> 
     </Storyboard> 
    </Window.Resources> 

    <Button x:Name="btnAdd" Content="Add" Width="69" Height="27"> 
     <i:Interaction.Triggers> 
      <i:EventTrigger EventName="MouseEnter"> 
       <ei:ControlStoryboardAction Storyboard="{StaticResource ButtonEffect_01}"/> 
      </i:EventTrigger> 
     </i:Interaction.Triggers> 
    </Button> 

我有3個更多按鈕btnDelete，btnUpdate，btnBack我可以對所有這些按鈕使用相同的Storyboard嗎？任何綁定方法？

爲了避免指定目標可以定義Button S的Style裏面故事板：

<Window.Resources> 
    <Style TargetType="Button"> 
     <Style.Triggers> 
      <EventTrigger RoutedEvent="MouseEnter"> 
       <BeginStoryboard> 
        <Storyboard AutoReverse="True" RepeatBehavior="Forever"> 
         <ColorAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Effect).(DropShadowEffect.Color)"> 
          <EasingColorKeyFrame KeyTime="0" Value="Black"/> 
          <EasingColorKeyFrame KeyTime="0:0:0.4" Value="#FFF3FF00"/> 
         </ColorAnimationUsingKeyFrames> 
        </Storyboard> 
       </BeginStoryboard> 
      </EventTrigger> 
     </Style.Triggers> 
    </Style> 
</Window.Resources>

您可以共享動畫多個對象，但是需要的動畫狀態的檢查。 爲了防止錯誤可以停止動畫前分配新的目標：

private void MouseEnter(object sender, PointerRoutedEventArgs e) 
    { 
     ButtonEffect_01.Stop(); 
     ButtonEffect_01.SetValue(Storyboard.TargetNameProperty, (sender as Button).Name); 
     ButtonEffect_01.Begin(); 
    }
