Dynamic addition of animation extender to panel

Hello everyone!

I've got a problem. :)

 I'm dynamically creating 20 panels. I need to add animation extender for each panel before adding it to controls. It's easy to add it using smart tag on aspx page, but I have to do it in .cs file.

So in my C# file I have:

Panel panel=new Panel();
AjaxControlToolkit.AnimationExtender AE=new AjaxControlToolkit.AnimationExtender();

AE.Animations.Insert(0, "<OnMouseOver><FadeOut Duration='0.5' minimumOpacity='0.7'></FadeOut></OnMouseOver>"); //I'm not sure in this line too :(

There is a similar thread, but I still have problems..

Thank you very much for your answers!
p.s sorry for my english ;)
