Dependency property identifier field: FromProperty
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.
To
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.
By
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.
