Gets a value that indicates whether the current navigator initiated the navigation.
Assembly: PresentationFramework (in PresentationFramework.dll)
This property indicates whether the current navigator is initiating the navigation or whether a parent navigator is being navigated. For example, the current navigator might be a frame inside a page that is being navigated to inside a parent navigator. You can use this property to determine whether to spin the globe on a Navigating event or to stop spinning the globe on a LoadCompleted event. If this property is false, the navigator's parent navigator is also navigating and the globe is already spinning. If this property is true, the navigation was initiated inside the current frame and you should spin the globe (or stop spinning the globe, depending on which event is being handled.)
