The following table summarizes how the From, To, and By properties can be used together or separately to determine an animation's target values.
Properties specified | Resulting behavior |
|---|---|
From | The animation progresses from the value specified by the From property to the base value of the property being animated or to a previous animation's output value, depending on how the previous animation is configured. |
From and To | The animation progresses from the value specified by the From property to the value specified by the To property. |
From and By | The animation progresses from the value specified by the From property to the value specified by the sum of the From and By properties. |
The animation progresses from the animated property's base value or a previous animation's output value to the value specified by the To property. | |
The animation progresses from the base value of the property being animated or a previous animation's output value to the sum of that value and the value specified by the By property. |

|---|
If you set both the To and By properties, the To property takes precedence and the By property is ignored. |
To use other interpolation methods or animate between more than two target values, use a DoubleAnimationUsingKeyFrames object.
To set a DoubleAnimation attribute to null in XAML, use an attribute value of {x:Null}.
