How to trigger the OnNavigatedFrom method of a page manually？

[SongOfYouth]

I want to notify a page to release some resource when close the TabViewItem which contains a frame which navigated to the page, the OnNavigatingFrom method is only triggered when the frame navigate to another page, is there any other way to trigger it?

The OnNavigatedFrom method of a page can be invoked by calling GetNavigationState on the frame object.
