ContentDialog中的UWP ListView无法滚动

Question

C＃UWP Windows 10

这是我的内容对话框的XAML代码：

 <Grid>
    <Grid.RowDefinitions>
        <RowDefinition Height="Auto"/>
        <RowDefinition Height="*"/>
    </Grid.RowDefinitions>
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="*"/>
        <ColumnDefinition Width="Auto"/>
    </Grid.ColumnDefinitions>

    .....

    <Grid Grid.Row="1" Grid.ColumnSpan="2">
        <ListView x:Name="MerchantList"                
            ItemTemplate="{StaticResource MerchantListViewTemplate}"
            SelectionMode="Single"
            SelectedValue="{Binding currItemId, Mode=TwoWay}"
            SelectedValuePath="Id"
            ShowsScrollingPlaceholders="True">
            <ListView.ItemContainerStyle>
                <Style TargetType="ListViewItem">
                    <Setter Property="HorizontalContentAlignment" Value="Stretch" />
                    <Setter Property="Margin" Value="0"/>
                    <Setter Property="Padding" Value="0"/>
                </Style>
            </ListView.ItemContainerStyle>
        </ListView>
    </Grid>
</Grid>

我需要向用户显示某些项目的列表，但ListView不会滚动。 如何解决？

Answer 1

尝试设置列和行的“非自动”大小（像素或星形，不要紧）。 我确实无法在文档中找出此行为的任何原因，但对我而言却有所帮助。

Answer 2

<Grid>
    <Grid.RowDefinitions>
        <RowDefinition Height="Auto"/>
        <RowDefinition Height="*"/>
    </Grid.RowDefinitions>
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="*"/>
        <ColumnDefinition Width="Auto"/>
    </Grid.ColumnDefinitions>



    <Grid Grid.Row="1" Grid.ColumnSpan="2">
        <ScrollViewer VerticalScrollMode="Enabled" HorizontalScrollMode="Enabled" VerticalScrollBarVisibility="Auto" HorizontalScrollBarVisibility="Auto">
        <ListView x:Name="MerchantList"                
        ItemTemplate="{StaticResource MerchantListViewTemplate}"
        SelectionMode="Single"
        SelectedValue="{Binding currItemId, Mode=TwoWay}"
        SelectedValuePath="Id"
        ShowsScrollingPlaceholders="True">
            <ListView.ItemContainerStyle>
                <Style TargetType="ListViewItem">
                    <Setter Property="HorizontalContentAlignment" Value="Stretch" />
                    <Setter Property="Margin" Value="0"/>
                    <Setter Property="Padding" Value="0"/>
                </Style>
            </ListView.ItemContainerStyle>
        </ListView>
        </ScrollViewer>
    </Grid>
</Grid>

尝试这个 ....
