From MSDN:

In Silverlight, the only event that you can use for an EventTrigger is the Loaded event. For other events, you should declare a storyboard in the Resources property, provide a Name value for the storyboard, and write an event handler that calls the Begin method on the named storyboard.

I imagine you could do something like this in your XAML (though I haven't tested it):

<Storyboard x:Name="MenuButtonShadowStoryboard">     <ColorAnimation Storyboard.TargetProperty="Color" Storyboard.TargetName="MenuButtonShadow"                     From="#FFFFFFFF" To="#FF000000" Duration="0:0:0.3">     </ColorAnimation> </Storyboard>  <ControlTemplate TargetType="Button">     <Border x:Name="Border" MouseEnter="Border_MouseEnter">         <!-- omitted for brevity -->     </Border> </ControlTemplate> 

And then your event handler would call the Begin method on the storyboard:

private void Border_MouseEnter(object sender, MouseEventArgs e) {     MenuButtonShadowStoryboard.Begin(); } 

You'll probably want to add something similar for the MouseLeave event, which makes the color go back to #FFFFFFFF.
