C# C Silverlight-放大水平列表框图像项

我有下面的列表框，它绑定到图像URL的数据库表。当应用程序运行时，可以单击每个单独的图像，并看到图像上出现一个浅蓝色的选择框，您可以知道何时将每个单独的图像选择为其所单击的图像。我希望能够做的是在单击每个图像时执行缩放。有人知道我可以通过修改下面我正在使用的代码来做到这一点吗！？这样做的原因是我需要在水平列表框中显示图像，这就是代码的作用

<ListBox x:Name="list1"  HorizontalAlignment="Left" RenderTransformOrigin="0.5,0.5"  Width="400"  d:LayoutOverrides="HorizontalAlignment">
                            <ListBox.ItemsPanel>
                                <ItemsPanelTemplate>
                                    <StackPanel Orientation="Horizontal"/>
                                </ItemsPanelTemplate>
                            </ListBox.ItemsPanel>
                            <ListBox.ItemTemplate>
                                <DataTemplate >
                                    <Image Width="100" Height="100" Stretch="Fill"  Source="{Binding LowResUrl}"/>
                                </DataTemplate>
                            </ListBox.ItemTemplate>
                        </ListBox>

您可以通过重写ControlTemplate来访问ListBoxItem控件的visualStateManager。在Expression Blend中选择ListBoxItem并编辑模板的副本。这将复制旧的ListBoxItem控件的样式和控件模板，为您提供一个良好的起点，以修改此ListBoxItem控件设置为处理的关键事件上发生的情况

完成此操作后，您可以在visual state manager中对各种各样的事件应用动画悬停、选择、禁用等

如果要对ItemsSource属性进行数据绑定，并且没有文字ListBoxItems来生成ListBoxItem样式，只需创建一个新的ListBox并向其添加一个ListBoxItem即可生成样式+控制模板。生成样式后，您可以通过在数据绑定ListBox控件的ItemContainerStyle属性上指定新创建的资源来更改nice数据绑定ListBox项的控件模板。

您可以使用此代码段您当前使用的ItemTemplate还有一个模板GeneratedEmContainerItemContainerStyle
