EventTrigger RoutedEvent amimation在WPF XAML

我想，当MyObject.IsGlowing = true所以我做了这个即将推出的动画（我在<DataTemplate>如果这能帮助）EventTrigger RoutedEvent amimation在WPF XAML

<Ellipse Width="100" Height="100" Name="MyEllipse"> 
    <Ellipse.Fill> 
     <RadialGradientBrush > 
      <GradientStop Offset="0" Color="Red" /> 
      <GradientStop Offset="0.5" Color="red" /> 
      <GradientStop Offset="1" Color="red"/> 
     </RadialGradientBrush > 
    </Ellipse.Fill> 
    <Ellipse.Triggers> 
     <DataTrigger Binding="{Binding Source=IsGlowing}" Value="True"> 
      <DataTrigger.EnterActions> 
       <BeginStoryboard Name="MyBeginStoryBoard"> 
        <Storyboard Name="MyStoryBoard" > 
         //Animation 
        </Storyboard> 
       </BeginStoryboard> 
      </DataTrigger.EnterActions> 
     </DataTrigger> 
    </Ellipse.Triggers> 
</Ellipse>

，但我得到这个错误“Triggers集合成员必须是类型EventTrigger的”所以我改成了

<Ellipse Width="100" Height="100" Name="MyEllipse"> 
    <Ellipse.Fill> 
     <RadialGradientBrush > 
      <GradientStop Offset="0" Color="Red" /> 
      <GradientStop Offset="0.5" Color="red" /> 
      <GradientStop Offset="1" Color="red"/> 
     </RadialGradientBrush > 
    </Ellipse.Fill> 
    <Ellipse.Triggers> 
     <EventTrigger RoutedEvent="?"> 
       <BeginStoryboard Name="MyBeginStoryBoard"> 
        <Storyboard Name="MyStoryBoard" > 
         //Animation 
        </Storyboard> 
       </BeginStoryboard> 
      </EventTrigger> 
    </Ellipse.Triggers> 
</Ellipse>

，但我不知道什么摆在RoutedEvent ...
