Open or close a storyboard
In Microsoft Expression Blend, you open a storyboard to turn on recording mode and add to the animation or other timelines that it contains. If you want to change the initial position or other initial properties of an object that is animated in a storyboard, you close the storyboard to return to the initial state of the object (and therefore turn off recording mode).
Under Objects and Timeline, click the Open a Storyboard button to view the storyboards that are in scope.
The Storyboard picker appears.
If you cannot locate the storyboard that you want to open, you might be in the wrong scope of the document. For example, you cannot open a storyboard that is defined in a control template unless you are in the editing scope of that template. For more information, see Create or edit a control template.
Select the storyboard that you want to open from the Storyboard picker.
Expression Blend 2 opens the storyboard and enters timeline recording mode.
