<Canvas x:Name="canvas" Margin="0,302,0,-302" Canvas.ZIndex="0" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" RenderTransformOrigin="0.5,0.5" >
<Canvas.Resources>
<Storyboard x:Name="TileAnimation">
<DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.RenderTransform).(CompositeTransform.TranslateY)" Storyboard.TargetName="canvas">
<EasingDoubleKeyFrame KeyTime="0" Value="-1.5"/>
<EasingDoubleKeyFrame KeyTime="0:0:0.4" Value="-252"/>

<CompositeTransform/>

</HubSection>
c# code behind:
Storyboard anim = (Storyboard)FindName("TileAnimation");
anim.Begin();

Yes, but complicated and not recommended, when you want to keep your code readable.
What I recommend is, develop a userControl which contains everything what is currently in your Template, and then design your animations in that control.
You can easily add this new control in the datatemplate instead of the code above. That makes it also easier to test the control.
