MVVM-Trigger Storyboard in Silverlight View Model

Question

I have several storyboards, in my opinion, that I would like to run from ViewModel, if possible. There is an easy way or an elegant way to do this. Here is what I am trying to do.

The user clicks the button → RelayCommand (in ViewModel), then the relay command should play the storyboard. In addition, one more thing, I would also like to run the storyboard animation myself in the ViewModel without any interaction.

    <i:Interaction.Triggers>
 <i:EventTrigger EventName="MouseLeftButtonDown">
    <cmd:EventToCommand Command="{Binding ButtonPress}"                                                     CommandParameterValue="RedButtonLight">
    </cmd:EventToCommand>
         </i:EventTrigger>
          </i:Interaction.Triggers>

I know that a long time ago. But I wrote a detailed blog post about Triggering Storyboards and MVVM.

Your viewmodel can then raise an event as part of the command, or at other times.

Here's how you can do this in a mixture without touching the xaml line or code: http://www.basarat.com/2011/05/expression-blend-starting-storyboard.html
