Try to specify:

Storyboard.TargetProperty="BorderBrush.Color"

and either specify:

BorderBrush="any-non-transparent-color"

or in the animation:

From="any-non-transparent-color"

That worked, Great. thank you. But why can't i use the "Transparent". It will be more powerfull !!! – Ziad Aug 30 '11 at 06:58
because if you use Transparent, you will have an animation starting from transparent and moving to tyransparent, so nothing happens. – Felice Pollano Aug 30 '11 at 07:08
As i'm learning more about animation, i can't bind the color property of the animation. i'm having an exception at run time !! any ideas? – Ziad Aug 30 '11 at 07:36
This is the new question. Thanks. http://stackoverflow.com/questions/7240480/binding-color-value-for-coloranimation – Ziad Aug 30 '11 at 08:24
Setting the StoryBoard.TargetPropertly="BorderBrush.Color" complains that BorderBrush has no Color property. Do you know is that solves the problem? – user3260977 Jun 10 '16 at 16:26
