Storyboard.GetCurrentIteration Method (FrameworkElement)
Assembly: PresentationFramework (in PresentationFramework.dll)
A clock's first iteration has a value of 1.
If this clock's timeline has an AutoReverse setting of true, a full iteration consists of a forward-reverse pair, not just one of these segments.
Regardless of its current iteration, seeking a clock returns its current iteration to 1. Restarting a clock also returns its current iteration to 1.
To use this method to retrieve information about a storyboard's clock, the storyboard must be controllable. To make a storyboard controllable in code, you must use the appropriate overload of the storyboard's Begin method and specify true to make it controllable. For an example, see How to: Control a Storyboard After It Starts.
