I would like to skin a wpf default checkbox to something custom. Since it does not really make sense to start off a entirely new control, i'd like to override the Windows Chrome template binding for the Bulletchrome sub component of the checkbox. However I cannot do this like I can with checkboxes for example.

tried using something like this to override the default style, but it seems to not compile like this

   <Style x:Key="cb_BULLETSTYLE" TargetType="{x:Type BulletDecorator}">
<Setter Property="OverridesDefaultStyle" Value="true"/>
<Setter Property="Template">
<Setter.Value>
 <ControlTemplate TargetType="{x:Type BulletDecorator}">
  <Border x:Name="Chrome" SnapsToDevicePixels="true" BorderBrush="{x:Null}" BorderThickness="0">
  </Border>
   <ControlTemplate.Triggers>
    <Trigger Property="IsMouseOver" Value="True">
     <Setter Property="Background" TargetName="Chrome" Value="#FF4C4C4C"/>
    </Trigger>
   </ControlTemplate.Triggers>
 </ControlTemplate>
</Setter.Value>
</Setter>
