Namespace:  System.Windows.Media.Animation
Assembly:  PresentationFramework (in PresentationFramework.dll)

public void SetSpeedRatio(
	double speedRatio
You cannot use methods in XAML.


Type: System.Double

A finite value greater than zero that is the new interactive speed ratio of the storyboard. This value is multiplied against the storyboard's SpeedRatio value to determine the storyboard's effective speed. This value does not overwrite the storyboard's SpeedRatio property. For example, calling this method and specifying an interactive speed ratio of 3 on a storyboard with a SpeedRatio of 0.5 gives the storyboard an effective speed of 1.5.

A controllable storyboard can pause, resume, seek, stop, and be removed. 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.
