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

Question

我想在 GridView 项目之间创建行分隔符，类似于以下必应新闻应用的屏幕截图

GridView XAML。 VariableSizedGridView 继承自 GridView，但允许项目具有不同的大小。

<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>

你需要改变gridview itemcontainerstyle如果你想在每个Gridview item.for那你需要编辑gridviewitem样式。

goto gridview item->右键->Edit template->Edit Copy->Ok.你会得到gridview item style

 <Page.Resources>
    <Style x:Name="Gridvieitemstyle" TargetType="GridViewItem">      
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="GridViewItem">
                    <Border x:Name="OuterContainer">                           
                           .
                           .
                        <!--I have removed visualstates.you add it later-->                          
                            .
                            .
