ItemsControl中的WPF中的縮放按鈕

Question

我創建了ItemsControl包含按鈕。想要縮放點擊按鈕。所有東西都是在Blend 4中創建的，所以我很驚訝，這在運行後不起作用。不知道有什麼問題。

<ItemsControl Grid.Row="1" ItemsSource="{Binding Symbols}"> 
     <ItemsControl.ItemTemplate> 
      <DataTemplate> 
       <DataTemplate.Resources> 
        <Storyboard x:Key="OnClick1"> 
         <DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.RenderTransform).(TransformGroup.Children)[0].(ScaleTransform.ScaleX)" Storyboard.TargetName="button"> 
          <EasingDoubleKeyFrame KeyTime="0:0:1" Value="2"/> 
         </DoubleAnimationUsingKeyFrames> 
         <DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.RenderTransform).(TransformGroup.Children)[0].(ScaleTransform.ScaleY)" Storyboard.TargetName="button"> 
          <EasingDoubleKeyFrame KeyTime="0:0:1" Value="2"/> 
         </DoubleAnimationUsingKeyFrames> 
        </Storyboard> 
       </DataTemplate.Resources> 
       <Button x:Name="button" cal:Message.Attach="[Event MouseDoubleClick] = [Action SymbolButton($dataContext)]" RenderTransformOrigin="0.5,0.5"> 
        <Button.RenderTransform> 
         <TransformGroup> 
          <ScaleTransform/> 
          <SkewTransform/> 
          <RotateTransform/> 
          <TranslateTransform/> 
         </TransformGroup> 
        </Button.RenderTransform> 
        <Button.Template> 
         <ControlTemplate> 
          <Label FontFamily="{Binding ElementName=cbLetterTypes, Path=EditValue.Name, Mode=OneWay}" Height="50" Width="50" Content="{Binding Value, Mode=OneWay}" ToolTip="{Binding ToolTip}" Background="White" HorizontalAlignment="Center" VerticalAlignment="Center" BorderThickness="1" BorderBrush="Black" HorizontalContentAlignment="Center" VerticalContentAlignment="Center"></Label> 
         </ControlTemplate> 
        </Button.Template>       
       </Button> 
       <DataTemplate.Triggers> 
        <EventTrigger RoutedEvent="ButtonBase.Click" SourceName="button"> 
         <BeginStoryboard x:Name="OnClick1_BeginStoryboard" Storyboard="{StaticResource OnClick1}"/> 
         <StopStoryboard BeginStoryboardName="OnClick1_BeginStoryboard"/> 
        </EventTrigger> 
       </DataTemplate.Triggers> 
      </DataTemplate> 
     </ItemsControl.ItemTemplate> 
     <ItemsControl.ItemsPanel> 
      <ItemsPanelTemplate> 
        <WrapPanel/> 
      </ItemsPanelTemplate> 
     </ItemsControl.ItemsPanel> 
     <ItemsControl.Template> 
      <ControlTemplate> 
       <ScrollViewer Margin="5" VerticalScrollBarVisibility="Auto"> 
        <ItemsPresenter/> 
       </ScrollViewer> 
      </ControlTemplate> 
     </ItemsControl.Template> 
    </ItemsControl>

<EventTrigger RoutedEvent="ButtonBase.Click" SourceName="button"> 
    <BeginStoryboard x:Name="OnClick1_BeginStoryboard" Storyboard="{StaticResource OnClick1}"/> 
    <StopStoryboard BeginStoryboardName="OnClick1_BeginStoryboard"/> 
</EventTrigger> 

你開始故事板和停止它的時候了，怎麼是這樣運作的呢？
