Scroll Vertically inside ListView when ListView is VerticalAlignment="Stretch"

How do we get the ListView to behave properly? I am trying to scroll vertically inside my ListView, and I was eventually able to get something to scroll vertically, but the ListView keeps expanding in height! and setting MaxHeight doesn't do anything.

    <StackPanel x:Name="ActivityLog" Margin="0, 201, 0, 0" HorizontalAlignment="Stretch" VerticalAlignment="Stretch">
        <ScrollViewer ScrollViewer.VerticalScrollBarVisibility="Visible">
            <ListView x:Name="ActivityList" ItemsSource="{Binding Activities}" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" BorderBrush="{x:Null}" HorizontalContentAlignment="Center" FontSize="14">
                <ListView.ItemTemplate>
                    <DataTemplate>
                        <TextBlock Text="{Binding Message}" Background="{x:Null}" HorizontalAlignment="Stretch" Padding="5" TextAlignment="Center" ScrollViewer.VerticalScrollBarVisibility="Auto" ScrollViewer.CanContentScroll="True" />
                    </DataTemplate>
                </ListView.ItemTemplate>
            </ListView>
        </ScrollViewer>
    </StackPanel>

I am at a loss. Please help. How do I get the listview to just scroll vertically only, and never change in height, and never display the horizontal scrollbars?

Remove the StackPanel. That prevents the ListView (or any other children) to have a delimited size. That's why you're not getting any scrollbars, because the ListView has an infinite height, as layout-ed by the StackPanel.

Besides, having a StackPanel with only 1 child makes no sense. It's supposed to "stack" its children.

Edit: Also remove the ScrollViewer, as the ListView already has a ScrollViewer inside of it as per the default Template. Unless of course you had changed the Default ControlTemplate for that.
