I'm having trouble applying a template to my checkboxes. I have the following template:

<ControlTemplate x:Key="TriStateRed" TargetType="{x:Type CheckBox}">
    <ControlTemplate.Triggers>
        <Trigger Property="IsChecked" Value="{x:Null}" >
            <Setter TargetName="path" Property="Data" Value="M 0 2.5 A 5 2.5 0 1 1 5 5 L 5 8 M 5 10 L 5 10" />
            <Setter TargetName="path" Property="Stroke" Value="Red" />
        </Trigger>
    </ControlTemplate.Triggers>
</ControlTemplate>

However, visual studio gives me the following error:

Cannot find the Trigger target 'path'. (The target must appear before any Setters, Triggers, or Conditions that use it.)

Can anyone make sense of this?
