how to fire StoryBoard on window loaded event (code behind)?

Question

I have a window with StoryBoard that stored in Window's resource as follows:

<Storyboard x:Key="FadeInStoryBoard"> <DoubleAnimation Storyboard.TargetName="GridNotificationWindow" From="0.01" To="1" Storyboard.TargetProperty="Opacity" Duration="0:0:2"/> <DoubleAnimation Storyboard.TargetName="GridNotificationWindow" From="1" To="0" Storyboard.TargetProperty="Opacity" Duration="0:0:2" BeginTime="0:0:6"/> </Storyboard>

And in code behind as follows:

private void Window_Loaded(object sender, RoutedEventArgs e) { Storyboard s = (Storyboard)this.TryFindResource("FadeInStoryBoard"); if(s!=null) { BeginStoryboard(s); } }

But it seems that is not working... If i set it in xaml, it's working:

<EventTrigger RoutedEvent="Window.Loaded" SourceName="GridNotificationWindow"> <BeginStoryboard x:Name="FadeInStoryBoard" > <Storyboard> <DoubleAnimation Storyboard.TargetName="GridNotificationWindow" From="0.01" To="1" Storyboard.TargetProperty="Opacity" Duration="0:0:2"/> <DoubleAnimation Storyboard.TargetName="GridNotificationWindow" From="1" To="0" Storyboard.TargetProperty="Opacity" Duration="0:0:2" BeginTime="0:0:6"/> </Storyboard> </BeginStoryboard> </EventTrigger>

How to can i fix for code behind?

set the target before calling BeginStoryboard

 Storyboard.SetTarget(s, TargetName);
