C# 使用XAML的Windows 8.1应用程序中GridView中的行分隔符

我想在GridView项目之间创建行分隔符，类似于Bing新闻应用程序的以下屏幕截图

GridView XAML。VariableSizeGridView继承自GridView，但允许项具有不同的大小

<controls:VariableSizedGridView
                    x:Name="newsGridView"
                    ItemsSource="{Binding TopItems}"
                    Margin="-9,-14,0,0"
                    SelectionMode="None"
                    IsSwipeEnabled="false"
                    IsItemClickEnabled="True"
                    ItemClick="news_ItemClick"
                    ItemTemplateSelector="{StaticResource mySelector}">
                    <GridView.ItemsPanel>
                        <ItemsPanelTemplate>
                            <VariableSizedWrapGrid ItemHeight="232" ItemWidth="320" />
                        </ItemsPanelTemplate>
                    </GridView.ItemsPanel>
                </controls:VariableSizedGridView>

如果要在每个gridview项下添加行，则需要更改gridview项ContainerStyle。为此，需要编辑gridview项样式

转到gridview项目->右键单击->编辑模板->编辑副本->确定。您将获得gridview项目样式

 <Page.Resources>
    <Style x:Name="Gridvieitemstyle" TargetType="GridViewItem">      
        <Setter Property="Template">
            <Setter.Value>

                    <Border x:Name="OuterContainer">
