I have something like this:

barProgress.BeginAnimation(RangeBase.ValueProperty, new DoubleAnimation(
    barProgress.Value, dNextProgressValue,
    new Duration(TimeSpan.FromSeconds(dDuration)));

Now, how would you stop that animation (the DoubleAnimation)? The reason I want to do this, is because I would like to start new animations (this seems to work, but it's hard to tell) and eventually stop the last animation...

To stop it, call BeginAnimation again with the second argument set to null.

Ah, that is just so... intuitive!

Who would of thought to call BeginAnimation() to stop one?

Place the animation in a StoryBoard. Call Begin() and Stop() on the storyboard to start to stop the animations.

+3  A: 

When using storyboards to control an animation, make sure you set the second parameter to true in order to set the animation as controllable:

public void Begin( FrameworkContentElement containingObject, bool isControllable )

Plus one to you, I was wondering why my animation did not respond to "Stop"!
+4  A: 

If you want the base value to become the effective value again, you must stop the animation from influencing the property. There are three ways to do this with storyboard animations:

  • Set the animation's FillBehavior property to Stop
  • Remove the entire Storyboard
  • Remove the animation from the individual property


How to: Set a Property After Animating It with a Storyboard



In my case I had to use two commands, my xaml has a button which fires a trigger, and its trigger fires the storyboard animation.

I've put a button to stop animation with this code behind:

MyBeginStoryboard.Storyboard.Begin(this, true);

I don't like it but it really works here. Give it a try!
