WPF: animate a custom dependency property?

Question

Hi everyone,

Let's say that I've defined a dependency like this:

     public class MySampleClass
    {public static DependencyProperty MyDoubleProperty = DependencyProperty.Register("MyDouble", typeof(double), typeof(MySampleClass));
    public double MyDouble
    {
        get
        {
            return (double)GetValue(MyDoubleProperty);
        }
        set
        {
            SetValue(MyDoubleProperty, value);
        }
    }
}

I'd like to apply a DoubleAnimation to this value. How can I do this? Always before, I've used DoubleAnimations by calling the BeginAnimation method of a UIElement.

Thanks for your help!

Answer 1

Are you trying to use a DoubleAnimation on a class that doesn't inherit from UIElement? If not, you should at least inherit from Animatable, or some other base class which also supports BeginAnimation.
