MouseEnter in EventTrigger ERROR

03-11-2008 1:49 PM |

 It's a example from SL SDK Documentation:

  <Rectangle
    x:Name="MyAnimatedRectangle"
    Width="100"
    Height="100"
    Fill="Blue">
    <Rectangle.Triggers>

      <!-- Animates the rectangle's opacity. -->
      <EventTrigger RoutedEvent="Rectangle.Loaded">
        <BeginStoryboard>
          <Storyboard>
            <DoubleAnimation
              Storyboard.TargetName="MyAnimatedRectangle"
              Storyboard.TargetProperty="Opacity"
              From="1.0" To="0.0" Duration="0:0:5" AutoReverse="True" RepeatBehavior="Forever" />
          </Storyboard>
        </BeginStoryboard>
      </EventTrigger>
    </Rectangle.Triggers>
  </Rectangle>

and it works, but if I change <EventTrigger RoutedEvent="Rectangle.Loaded"> to <EventTrigger RoutedEvent="Rectangle.MouseEnter"> 

I have parser error "Attribute Rectangle.MouseEnter value is out of range."

Waiting for any ideas ))
