Question

我在itemspage上进行水平滚动时遇到了一些问题。

如果默认网格模板有更多数据并且屏幕调整到它，则它将水平滚动。但我也希望在页面中添加一个列表视图。

基本上，我希望页面与网格水平滚动，然后滚动到列表。

目前，它只是部分切断了“MessageList”。

参见下面的XAML：

    <common:LayoutAwarePage.Resources>

    <!-- Collection of items displayed by this page -->
    <CollectionViewSource
        x:Name="itemsViewSource"
        Source="{Binding Items}"
        d:Source="{Binding AllGroups, Source={d:DesignInstance IsDesignTimeCreatable=True, Type=data:SampleDataSource}}"/>
</common:LayoutAwarePage.Resources>

<!--
    This grid acts as a root panel for the page that defines two rows:
    * Row 0 contains the back button and page title
    * Row 1 contains the rest of the page layout
-->
<Grid Style="{StaticResource LayoutRootStyle}" ScrollViewer.HorizontalScrollBarVisibility="Auto" Margin="0,0,0.429,0.429">
    <Grid.RowDefinitions>
        <RowDefinition Height="140"/>
        <RowDefinition Height="*"/>
    </Grid.RowDefinitions>


    <VisualStateManager.VisualStateGroups>

        <!-- Visual states reflect the application's view state -->
        <VisualStateGroup x:Name="ApplicationViewStates">
            <VisualState x:Name="FullScreenLandscape"/>
            <VisualState x:Name="Filled"/>

            <!-- The entire page respects the narrower 100-pixel margin convention for portrait -->
            <VisualState x:Name="FullScreenPortrait">
                <Storyboard>
                    <ObjectAnimationUsingKeyFrames Storyboard.TargetName="backButton" Storyboard.TargetProperty="Style">
                        <DiscreteObjectKeyFrame KeyTime="0" Value="{StaticResource PortraitBackButtonStyle}"/>
                    </ObjectAnimationUsingKeyFrames>
                    <ObjectAnimationUsingKeyFrames Storyboard.TargetName="itemGridView" Storyboard.TargetProperty="Padding">
                        <DiscreteObjectKeyFrame KeyTime="0" Value="96,136,86,56"/>
                    </ObjectAnimationUsingKeyFrames>
                </Storyboard>
            </VisualState>

            <!--
                The back button and title have different styles when snapped, and the list representation is substituted
                for the grid displayed in all other view states

            <VisualState x:Name="Snapped">
                <Storyboard>

将GridView，ListView和ListView换成ScrollViewer，并设置以下属性：

<ScrollViewer HorizontalScrollMode="Auto" 
              HorizontalScrollBarVisibility="Auto"
              VerticalScrollMode="Disabled"
              VerticalScrollBarVisibility="Hidden">
<!-- The elements you want to be horizontally scrollable goes here -->
</ScrollViewer>
