Using event triggers with Storyboards and other UIElements?

Question

I'm trying to get a basic EventTrigger to work with a Storyboard and a UIElement. I'm using GalaSoft MVVMLight on Windows Phone 7.

Here's what I have for an ellipse.

<Ellipse x:Name="EquipmentSlot_CPU" Height="55" Stroke="Black" Fill="#FFA1A1A1" Margin="1,0,0,0" VerticalAlignment="Top"
        Width="55" HorizontalAlignment="Left">
    <Ellipse.Triggers>
        <EventTrigger RoutedEvent="UIElement.MouseLeftButtonDown">
            <BeginStoryboard Storyboard="{StaticResource InventorySlotTransition_Start}" />
        </EventTrigger>
    </Ellipse.Triggers>
    <Custom:Interaction.Triggers>
        <Custom:EventTrigger EventName="MouseLeftButtonDown">
            <Command:EventToCommand x:Name="cpu_Click"
                    Command="{Binding InventoryViewModel.Command_EquipmentSlotSelected, Mode=OneWay, Source={StaticResource Locator}}"
                    CommandParameter="CPU" />
        </Custom:EventTrigger>
    </Custom:Interaction.Triggers>
</Ellipse>

However, I get an XAMLParseException stating that it Failed to assign to property 'System.Windows.EventTrigger.RoutedEvent'.

I'd like to be able to get this to work with a Storyboard as well, but that seems to come with it's own set of issues.

What version of WP are you targeting and what version of System.Windows.Interactivity are you using? — Derek Beattie, Sep 05 '11 at 02:51
With that error, first thing I'd try would be: Custom:EventTrigger EventName="**UIElement**.MouseLeftButtonDown" — XAMeLi, Sep 05 '11 at 09:23
@Derek - Currently I'm targeting WP 7.1 (mango) and using System.Windows.Interactivity version 3.8.5.0. — Andrew Black, Sep 06 '11 at 01:24
@XAMeLi - Sorry, I should have clarified what part wasn't working. The only part that doesn't work is the Ellipse.Triggers. The Custom:EventTrigger works fine. — Andrew Black, Sep 06 '11 at 01:26
@Claus - This is just temporary for testing purposes. In the final build I plan to make the control a button and just use the Click event. — Andrew Black, Sep 06 '11 at 01:27
