I am trying to build some notification control in Silverlight. When I click the notification icon it shows/hides the notification window which contains all notification messages.

I have an ItemsControl in view whose ItemsSource is binded to an ObservableCollection in presenter.

I want to invoke a Storyboard defined in view whenever ItemSource (i.e. ObservableCollection in Presenter) is updated.

Is it possible with EventTriggers? if yes how?

Can I invoke Storyboard from presenter, if yes how? And is it a bad idea to invoke Storyboard from presenter?

    Here is a complete example using an Expression Blend behavior BeginStoryBoardAction together with a custom DataChangedTrigger: wp7 listboxitem animation on bound data changes (mvvm)

    You can still use Blend behaviors even if you don’t have Blend, you just need the Blend SDK.
