I'm styling a listbox to have some effects like MouseLeave and UnSelect fadeout. It works when no item selected. But once some items are selected one by one, effects not working for them anymore! even if they're not selected.
Ideal behavior is when, items behave constantly in response to events and property changes. I want to have List Box items that respond to MouseOver and MouseLeave events when they're not selected, and respond to Unselect property change.

You are never stopping the storyboards, so eventually they are all running.I have added file FillBehavior="Stop" in storyboard.You can set the FillBehavior of the Storyboards to Stop so that the Storyboard will stop setting the value after it completes.
