UWP Listview in Gridview not increasing

问题

I've got a GridView to display some data. Each of the GridView items is a ListView which is increasing during runtime. I'd like the GridView to increase as well - but it is only showing a scrollbar inside the GridView item. One further requirement would be that each GridView Item should be aligned on top of the item.

<GridView ItemsSource="{Binding}" ScrollViewer.VerticalScrollBarVisibility="Disabled" Width="1080">
<GridView.ItemTemplate>
    <DataTemplate>                     
        <ListView ItemsSource="{Binding ListData}" HorizontalAlignment="Center">
            <ListView.ItemTemplate>
                <DataTemplate >
                    <Grid>
                        <Grid.ColumnDefinitions>
                            <ColumnDefinition Width="Auto"/>
                            <ColumnDefinition Width="Auto"/>
                            <ColumnDefinition Width="*"/>
                        </Grid.ColumnDefinitions>
                        <TextBlock Text="&#x1f382;" 
                                FontSize="20" 
                                Grid.Column="0"
                                Margin="0,0,10,10"
                                FontFamily="Sergoe UI"
                                Style="{StaticResource BasicTextBlock}"/>
                        <TextBlock Text="{Binding NameString, Converter={StaticResource DataBindingDebugConverter}}" 
                                Grid.Column="2"
                                Margin="10,0,0,0"
                                FontSize="16"
                                Style="{StaticResource BasicTextBlock}"/>
                    </Grid>
                </DataTemplate>
            </ListView.ItemTemplate>
            <ListView.ItemContainerStyle>
                <Style TargetType="ListViewItem">
                    <Setter Property="Padding" Value="0"/>
                    <Setter Property="Margin" Value="0,0,0,0"/>
                    <Setter Property="VerticalContentAlignment" Value="Stretch"/>
                </Style>
            </ListView.ItemContainerStyle>
        </ListView> 
    </DataTemplate>
</GridView.ItemTemplate>
<GridView.ItemContainerStyle>
    <Style TargetType="GridViewItem">
        <Setter Property="Padding" Value="0"/>
        <Setter Property="Margin" Value="0,20,0,0"/>
        <Setter Property="Width" Value="360" />
    </Style>
</GridView.ItemContainerStyle>
</GridView>

the correct answer for this question is (based on the hint of JustinXL)

<GridView ItemsSource="{Binding}" ScrollViewer.VerticalScrollBarVisibility="Disabled" Width="1080">
<GridView.ItemTemplate>
    <DataTemplate>
        <ItemsControl ItemsSource="{Binding ListData, Converter={StaticResource DataBindingDebugConverter}}" x:Name="BirthdayListView" HorizontalAlignment="Center" Margin="0,20,0,0">
            <ItemsControl.ItemTemplate>
                <DataTemplate>
                    <Grid>
                        <Grid.ColumnDefinitions>
                            <ColumnDefinition Width="Auto"/>
                            <ColumnDefinition Width="Auto"/>
                            <ColumnDefinition Width="*"/>
                        </Grid.ColumnDefinitions>
                        <TextBlock Text="&#x1f382;" 
                                    FontSize="16" 
                                    Grid.Column="0"
                                    Margin="0,0,10,10"
                                    FontFamily="Sergoe UI"
                                    Style="{StaticResource BasicTextBlock}"/>
                        <TextBlock Text="{Binding NameString, Converter={StaticResource DataBindingDebugConverter}}" 
                                    Grid.Column="2"
                                    Margin="10,0,0,0"
                                    FontSize="16"
                                    Style="{StaticResource BasicTextBlock}"/>
                    </Grid>
                </DataTemplate>
            </ItemsControl.ItemTemplate>
        </ItemsControl>
    </DataTemplate>
</GridView.ItemTemplate>
<GridView.ItemContainerStyle>
    <Style TargetType="ContentControl">
        <Setter Property="Padding" Value="0"/>
        <Setter Property="Margin" Value="0,20,0,0"/>
        <Setter Property="Width" Value="360" />
        <Setter Property="VerticalContentAlignment" Value="Top" />
    </Style>
</GridView.ItemContainerStyle>
</GridView>
