AnimationExtender in Repeater

[Ve]

Hi, I want to use AnimationExtender control in Repeater.
I want to text display, when user move over image his cursor.
I downloaded example from:
http://asp.net/learn/ajax-videos/video-117.aspx
and everything is ok, because there is only one button that triggers action.

My problem is, thas I want to use AnimationExtender control in Repeater.
There is one atribute that point on div, where the animation will
display - AnimationTarget="flyout"
When I put it in repeater all animations were in the same place.
So I tried to dinamicaly set this property
<Parallel AnimationTarget='<%#"flyout"+Eval("id").ToString() %>' ...

but I had the exception:

The 'Animations' property of 'ajaxToolkit:AnimationExtender' does not
allow child objects.

So my question is, how to use this control in repeater, and have
animation in many places ?

Thanks for help
