C# WPF listBox vertical alignment

I have a listBox with a checkbox I want to manage the alignment through setting the vertical alignment.
I have seen several solution here e.g. set verticalContentAlignment or verticalAlignment to top but that didn't work.
I've also seen some setting a style but couldn't manage to make it done.
What I'd like is to know WHY the ONLY element is down there. I can't understand why it's stuck in the middle.
Here's my code:
<ListBox x:Name="lb2Tab3" HorizontalContentAlignment="Stretch" FontSize="{StaticResource BUTTON_FONTSIZE}" Background="{x:Null}" BorderBrush="{x:Null}" Margin="0,0,0.8,0" >
<CheckBox x:Name="cbEasyRunManagesPcDmis" Margin="20" Content="EasyRun Manages PC-DMIS" HorizontalAlignment="Left" VerticalAlignment="Top" Click="cbTouchScreen_Click" />
</ListBox>
thanx for any help

You need to align the ListBox
<ListBox x:Name="lb2Tab3" HorizontalContentAlignment="Stretch"
VerticalContentAlignment="Top"
If that does not work then post more of your XAML
So the problem was related with the fact that there are several listBox one on top of the other. I thought that making them hidden was enough but when I painted the second listBox in black I saw that it was not starting from the top (see image).
So the solution was to set Visibility = Collapsed for all the listbox that are not in use.
Thanks to kirotab for putting me on the right path. Not sure if I can vote your comment.

In my data template I am placing LongListselector... which also needs a template. but the SpacesTemplate that is defined outside the current datatemplate cannot be seen. any ideas how to reference the datatemplate "SpacesTemplate" from within the datatemplate "OrganisationsItemTemplate"
Xaml is read top down, if you want to use SpacesTemplate inside OrganisationsItemTemplate you will have to put SpacesTemplate before OrganisationsItemTemplate in the Xaml

Just glancing at your code quickly, the only thing you should need to do is change this line:
<ListBox x:Name="CategoryBoards" Background="Transparent" BorderThickness="0"
Margin="0" Padding="0" HorizontalContentAlignment="Stretch"
ItemContainerStyle="{StaticResource ListBoxItemStyle}"
ItemsSource="{Binding }">
to this:
<ListBox x:Name="CategoryBoards" Background="Transparent" BorderThickness="0"
Margin="0" Padding="0" HorizontalContentAlignment="Stretch"
ItemContainerStyle="{StaticResource ListBoxItemStyle}"
ItemsSource="{Binding Boards}">
The DataContext of your inner ListBox will be the Category, so the source of that binding is, implicitly, the Category.
