Reversing an animation in Silverlight on button press or any other event?

Ok, the way I got it working was by pausing the animation, swapping the To and From values, and using the Seek method to move the animation forward by a set amount. The amount I needed it to move forward is "Duration.TimeSpan() - GetCurrentTime()", but accessing Duration seems to throw an exception (Operation not valid for the current state of the object).

For now, I just hard coded the Duration value for a test and seems to be working fine.

I guess for a real implementation the Duration can be bound to some value and the calculation can use that value too.

1 I did more or less the same in a similar situation. My problem with getting the StoryBoard. Duration was that the value was Automatic and I had to navigate to the actual animation classes in the storyboard and get their durations.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
