Setter not working for margin on user control in WPF

Question

I have created a UserControl that is working just fine. If I set the margin in code all goes well:

<cbtn:BillLister Margin="10,5,10,5" />

However, when i try to set it for everyone of those that are in the wrappannel they are in, this doesn't work:

<WrapPanel.Resources>
  <Style TargetType="cbtn:BillLister">
    <Style.Setters>
      <Setter Property="Margin" Value="150,35,50,35" />
      <Setter Property="Background" Value="Black"/>
    </Style.Setters>
  </Style>

The Background property is working however, so i know that it is targeting the correct UserControls.

I did find this: How to give my custom control an overridable default margin? I tried what he did in there, and still no change.

public partial class BillLister : UserControl
{
    public BillLister()
    {
        InitializeComponent();     
        Labelcount.Content = "0";
    }

    static BillLister()
    {
        MarginProperty.OverrideMetadata(typeof(BillLister), new FrameworkPropertyMetadata(new Thickness(30, 130, 30, 30)));            
    }
...

Does anyone have any idea what might be going on here? I would hate to have to set the margin on each one manually.

Update to clarify: When trying the second version i don't use the inline margin from the first one. Also, the margin fromthe second example is not applied at all.

When you try your second approach do you still have inline margin given Margin="10,5,10,5"? — Nitin, Mar 31 '16 at 10:00
No, it's to replace the inline one that i'm trying to do that. — Kristof Nachtergaele, Mar 31 '16 at 10:33
With or Without the static constructor in the second one makes no difference. — Kristof Nachtergaele, Mar 31 '16 at 10:34
