Question

使用这个简单的XAML代码：

<Grid Background="{StaticResource ApplicationPageBackgroundThemeBrush}">
    <Grid Width="230" Height="300" Background="Red" Margin="0">
        <FlipView Background="Blue" Margin="0" Padding="0" BorderThickness="0"/>
    </Grid>
</Grid>

结果：

如何删除显示红色网格背景的flipview透明“边距”？

Answer 1

这是因为FlipView控件的默认样式。

要删除它，您需要复制此默认样式（在下面发布）并删除边框中的边距：

<Style x:Key="FlipViewStyle1" TargetType="FlipView">
        <Setter Property="Background" Value="Transparent"/>
        <Setter Property="BorderThickness" Value="0"/>

        <Setter Property="ScrollViewer.IsVerticalRailEnabled" Value="False"/>
        <Setter Property="ScrollViewer.IsHorizontalScrollChainingEnabled" Value="True"/>
        <Setter Property="ScrollViewer.IsVerticalScrollChainingEnabled" Value="True"/>
        <Setter Property="ScrollViewer.IsDeferredScrollingEnabled" Value="False"/>
        <Setter Property="ScrollViewer.BringIntoViewOnFocusChange" Value="True"/>
        <Setter Property="ItemsPanel">

                </ItemsPanelTemplate>

只需更改边框上的margin属性：

<Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" Margin="3">

by：

<Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" Margin="0">

Answer 2

FlipView往往保持小幅度。如果你强制它Margin=-3它会显示你想要的输出。或者，您可以添加另一个元素，以确保没有“光”从后面传递而没有黑客。

<Grid Background="{StaticResource ApplicationPageBackgroundThemeBrush}">
    <Grid Width="230" Height="300" Background="Red">
        <Grid Background="Blue">
            <FlipView/>
        </Grid>
    </Grid>
</Grid>
