| Return code | Description |
|---|---|
|
The transition has not been added to the storyboard. |
Remarks
A keyframe represents a moment in time within a storyboard and can be used to specify the start and end times of transitions. Because keyframes can be added at the ends of transitions, their offsets from the start of the storyboard may not be known until the storyboard is playing.
