When ListView HorizontalAlignment=Stretch it no longer scrolls? - xaml

Question

I'm working on a WP WinRT app that contains a page with a ListView that needs to scroll if it's content (binding) is longer than the screen. Now I want this app to be scalable across different screensizes, but right now the scrollviewer just falls of the page, and does not snap to the bottom of the screen.
XAML:
<Grid x:Name="LayoutRoot">
<Grid.ChildrenTransitions>
<TransitionCollection>
<EntranceThemeTransition FromHorizontalOffset="100"/>
</TransitionCollection>
</Grid.ChildrenTransitions>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<!-- Title Panel -->
<StackPanel Grid.Row="0" Margin="19,0,0,0">
<TextBlock Text="TITLE" Style="{ThemeResource TitleTextBlockStyle}" Margin="0,12,-0.167,0">
<TextBlock.Foreground>
<SolidColorBrush Color="{StaticResource LightForegroundColor}"/>
</TextBlock.Foreground>
</TextBlock>
<TextBlock Text="subtitle Margin="0,-6.5,0,26.5" Style="{ThemeResource HeaderTextBlockStyle}" CharacterSpacing="{ThemeResource PivotHeaderItemCharacterSpacing}" FontSize="48">
<TextBlock.Foreground>
<SolidColorBrush Color="White"/>
</TextBlock.Foreground>
</TextBlock>
<TextBlock Margin="0,0,18.833,0" TextWrapping="Wrap" Text="This is a textblock with some random text." VerticalAlignment="Top" FontSize="14.667" Style="{StaticResource BaseTextBlockStyle}">
<TextBlock.Foreground>
<SolidColorBrush Color="{StaticResource DarkForegroundColor}"/>
</TextBlock.Foreground>
</TextBlock>
</StackPanel>
<ListView Grid.Row="1" Margin="0,10,0,0">
<ListView.ItemTemplate>
<DataTemplate>
<StackPanel Margin="0,11,0,0">
<TextBlock Style="{ThemeResource ListViewItemTextBlockStyle}" Text="Text"/>
</StackPanel>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</Grid>
