DataTemplate in HubSection does not reach full height

I have the following code:

<HubSection x:Name="modules_section" ...>
    <DataTemplate>
        <StackPanel Orientation="Vertical">
        ..................................

How can I get the StackPanel to take the entire height of the HubSection?

VerticalAlignment = "Stretch" does not do the job.

I also tried using binding via

<StackPanel Height={Binding ElementName=modules_section, Path=ActualHeight}" ...>

but the Actualheight section of the hub seems to be 0 (I also tried to set it in encoding and debug to see the value).
