Typically, updates and notifications occur automatically after the layout is updated in Silverlight. (The update occurs in response to the LayoutUpdated event.) However, properties can change even when no rendering changes occur. For example, the visual rendering usually does not change when the values of an element's ItemStatus or Name properties change. Call InvalidatePeer when your code changes properties that do not change the visual state. InvalidatePeer forces re-evaluation of automation properties and raises property change notifications to automation clients.
