                                        <ColorAnimation AutoReverse="True" RepeatBehavior="Forever" Storyboard.TargetProperty="BorderBrush" Duration="00:00:01" To="Transparent"></ColorAnimation>

                                </BeginStoryboard>
                            </Trigger.EnterActions>
                        </Trigger>
                    </Style.Triggers>
                </Style>
        </Border.Style>

Solution

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 !!!

[Felice Pollano]

because if you use Transparent, you will have an animation starting from transparent and moving to tyransparent, so nothing happens.

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?

This is the new question. Thanks. stackoverflow.com/questions/7240480/…

Setting the StoryBoard.TargetPropertly="BorderBrush.Color" complains that BorderBrush has no Color property. Do you know is that solves the problem?
