WP7: LayoutTransform a ListBoxItem - xaml

Question

Here's my XAML:
<ListBox x:Name="MyListBox" FontSize="40"
SelectionChanged="MyListBox_SelectionChanged">
</ListBox>
In this code-behind (below), I am attempting to animate a delete action. When the item is selected I delete it. I visually animate it with a ScaleTransform. In WPF I would use a LayoutTransform, but since I only have RenderTransform in WP/SL, I am using RenderTransform - and as a result the surrounding layout is not responding to the change in size. The record is still correctly deleted, but the visual effect is diminished.
Is there a way to do this in WP? Is there a way to resize a ListBoxItem so that the surrounding content responds?
ObservableCollection<string> m_Data;
public MainPage()
{
InitializeComponent();
m_Data = new ObservableCollection<string>
{ "One", "Two", "Three", "Four" };
MyListBox.ItemsSource = m_Data;
}
private void MyListBox_SelectionChanged(object sender,
SelectionChangedEventArgs e)
{
// fetch ListBoxItem
if (e.AddedItems.Count == 0)
return;
var _Data = e.AddedItems[0] as string;
var _Item = MyListBox.ItemContainerGenerator
.ContainerFromItem(_Data) as ListBoxItem;
// setup to resize using scale transform
var _Scale = new ScaleTransform
{
CenterX = _Item.RenderSize.Width / 2,
CenterY = _Item.RenderSize.Height / 2,
ScaleX = .99,
ScaleY = .99
};
_Item.RenderTransform = _Scale;
// setup storyboard
var _Story = new Storyboard();
_Story.Completed += (s, e1) =>
{
// remove data from collection
m_Data.Remove(_Data);
};
// animate scale X
var _AnimationX = new DoubleAnimation
{
To = .01,
Duration = TimeSpan.FromSeconds(2),
};
_Story.Children.Add(_AnimationX);
Storyboard.SetTarget(_AnimationX, _Scale);
Storyboard.SetTargetProperty(_AnimationX,
new PropertyPath(ScaleTransform.ScaleXProperty));
// animate scale Y
var _AnimationY = new DoubleAnimation
{
To = .01,
Duration = TimeSpan.FromSeconds(2),
};
_Story.Children.Add(_AnimationY);
Storyboard.SetTarget(_AnimationY, _Scale);
Storyboard.SetTargetProperty(_AnimationY,
new PropertyPath(ScaleTransform.ScaleYProperty));
_Story.Begin();
}

You can also use LayoutTransform on Windows Phone so I would just use that. .
