Question

我有一个垂直的ListView。它承载多个水平ListView。

示例：

<ListView ScrollViewer.HorizontalScrollMode="Disabled" ScrollViewer.HorizontalScrollBarVisibility="Disabled" ScrollViewer.VerticalScrollMode="Enabled" ScrollViewer.VerticalScrollBarVisibility="Hidden">
    <ListView ScrollViewer.HorizontalScrollMode="Enabled" ScrollViewer.HorizontalScrollBarVisibility="Hidden">
            <ListView.ItemsPanel>
                    <ItemsPanelTemplate>
                            <ItemsWrapGrid Orientation="Vertical" MaximumRowsOrColumns="1"/>
                    </ItemsPanelTemplate>
            </ListView.ItemsPanel>
            <Grid Width="50" Height="50" Background="Green"/>
            <Grid Width="50" Height="50" Background="Green"/>
            <Grid Width="50" Height="50" Background="Green"/>
            <Grid Width="50" Height="50" Background="Green"/>
            <Grid Width="50" Height="50" Background="Green"/>
            <Grid Width="50" Height="50" Background="Green"/>
            <Grid Width="50" Height="50" Background="Green"/>
    </ListView>
    <ListView ScrollViewer.HorizontalScrollMode="Enabled" ScrollViewer.HorizontalScrollBarVisibility="Hidden">
            <ListView.ItemsPanel>
                    <ItemsPanelTemplate>
                            <ItemsWrapGrid Orientation="Vertical" MaximumRowsOrColumns="1"/>
                    </ItemsPanelTemplate>
            </ListView.ItemsPanel>
            <Grid Width="50" Height="50" Background="Green"/>
            <Grid Width="50" Height="50" Background="Green"/>
            <Grid Width="50" Height="50" Background="Green"/>
            <Grid Width="50" Height="50" Background="Green"/>
            <Grid Width="50" Height="50" Background="Green"/>
            <Grid Width="50" Height="50" Background="Green"/>
            <Grid Width="50" Height="50" Background="Green"/>
    </ListView>
</ListView>

现在滚动根本不起作用，只能通过触摸进行操作。

我需要使用鼠标滚轮进行滚动以使其只能在垂直方向上工作，并进行操纵以保持其当前状态（垂直和水平方向）。

我在这里做什么错了？

对于水平ListView，您可以编辑默认的ItemsPanelTemplate并将Orientation设置为Horizontal，然后将crollViewer.HorizontalScrollMode设置为Enabled。您也可以直接使用以下水平ListView样式。我已经按照您的代码进行了测试，该样式有效。

<Style x:Key="MyListViewStyle" TargetType="ListView">
    <Setter Property="IsTabStop" Value="False"/>
    <Setter Property="TabNavigation" Value="Once"/>
    <Setter Property="IsSwipeEnabled" Value="True"/>
    <Setter Property="ScrollViewer.HorizontalScrollBarVisibility" Value="Disabled"/>
    <Setter Property="ScrollViewer.VerticalScrollBarVisibility" Value="Auto"/>
    <Setter Property="ScrollViewer.HorizontalScrollMode" Value="Disabled"/>
    <Setter Property="ScrollViewer.IsHorizontalRailEnabled" Value="False"/>
    <Setter Property="ScrollViewer.VerticalScrollMode" Value="Enabled"/>
    <Setter Property="ScrollViewer.IsVerticalRailEnabled" Value="True"/>
    <Setter Property="ScrollViewer.ZoomMode" Value="Disabled"/>
    <Setter Property="ScrollViewer.IsDeferredScrollingEnabled" Value="False"/>
    <Setter Property="ScrollViewer.BringIntoViewOnFocusChange" Value="True"/>
    <Setter Property="UseSystemFocusVisuals" Value="{StaticResource UseSystemFocusVisuals}"/>
    <Setter Property="ItemContainerTransitions">
        <Setter.Value>
            <TransitionCollection>
                <AddDeleteThemeTransition/>
                <ContentThemeTransition/>
                <ReorderThemeTransition/>
                <EntranceThemeTransition IsStaggeringEnabled="False"/>
            </TransitionCollection>
        </Setter.Value>
    </Setter>
    <Setter Property="ItemsPanel">
        <Setter.Value>

                                  IsHorizontalScrollChainingEnabled="{TemplateBinding ScrollViewer.IsHorizontalScrollChainingEnabled}"
                                  TabNavigation="{TemplateBinding TabNavigation}"

                                        Padding="{TemplateBinding Padding}"/>
                    </ScrollViewer>
                </Border>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>
