✅ TreeView scrollbar isn't visible

I have a tree view, and I want it to be scrollable when there are many items. I have tried to put it in the ScrollView and set ScrollViewer.VerticalScrollBarVisibility="Auto" , but it doesn't solve the problem.

<StackPanel VerticalAlignment="Stretch">
    <Button Command="{s:Action OnLoadAsync}">Load</Button>
    <TreeView ScrollViewer.VerticalScrollBarVisibility="Auto" BorderThickness="0" ItemsSource="{Binding Path=Directories}">
        <TreeView.Resources>
            <HierarchicalDataTemplate DataType="{x:Type models:NavigationPaneItem}" ItemsSource="{Binding Children}">
                <TextBlock Text="{Binding DisplayName}"/>
            </HierarchicalDataTemplate>
        </TreeView.Resources>
    </TreeView>
</StackPanel>

dont use stackpanel use a grid stackpanel gives it internally the size it wants is something to do with the stackpanel providing as much height as the inside content wants so the scrollviewer never saw the need to show up and say hi
