How can I apply a style from resources to a checkbox within a DataGridCheckBoxColumn?

<tk:DataGrid.Columns>
	<tk:DataGridTextColumn Header="Event ID" Binding="{Binding ID}" MinWidth="50" IsReadOnly="True" />
	<tk:DataGridTextColumn Header="Name" Binding="{Binding Name}" MinWidth="200" Width="*" />
	<tk:DataGridCheckBoxColumn Header="Audio" Binding="{Binding FrontAudioEnabled}" />
	<tk:DataGridTemplateColumn Header="In Point" MinWidth="100">
		<tk:DataGridTemplateColumn.CellTemplate>
			<DataTemplate>
