Comment personnaliser le style de Case à cocher dans WPF

Je suis juste de commencer l'étude de WPF, donc je suis familier avec le style et le modèle.
Je veux personnaliser un CheckBox avec un Image et deux Labels comme ceci:

Comment puis-je faire?

.xaml

<Window x:Class="WpfApplication4.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525">

    <StackPanel>
        <CheckBox Width="150" 
                  Height="40" 
                  Margin="4" 
                  Padding="4,0,0,0">
            <Grid Background="#FFEEEEEE" 
                  Width="130"
                  MaxWidth="Infinity">
                <Grid.ColumnDefinitions>
                    <ColumnDefinition Width="Auto" />
                    <ColumnDefinition Width="*" />
                </Grid.ColumnDefinitions>
                <Grid.RowDefinitions>
                    <RowDefinition Height="*"/>
                    <RowDefinition Height="*"/>
                </Grid.RowDefinitions>
                <Image Grid.Row="0"
                       Grid.RowSpan="2"
                       Grid.Column="0"
                       Margin="5" 
                       Source="/WpfApplication4;component/Images/LargeIcon.png" />
                <Label Grid.Row="0"
                       Grid.Column="1" 
                       Padding="0">
                    Label1
                </Label>
                <Label Grid.Row="1"
                       Grid.Column="1" 
                       Padding="0">
                    Label2
                </Label>
            </Grid>
        </CheckBox>
    </StackPanel>
</Window>

Edit:

.xaml

<Application x:Class="WpfApplication4.App"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:d="http://schemas.microsoft.com/expression/blend/2006" 
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
             StartupUri="MainWindow.xaml">

    <Application.Resources>
        <Style x:Key="MyCheckBox" 
               TargetType="{x:Type CheckBox}">
            <Setter Property="Width" Value="150"/>
            <Setter Property="Height" Value="40"/>
            <Setter Property="Margin" Value="4"/>
            <Setter Property="Padding" Value="4,0,0,0"/>
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="{x:Type CheckBox}">
                        <DockPanel Background="#FFEEEEEE" 
                                   Height="34"
                                   Width="130">
                            <Image DockPanel.Dock="Left"
                                   Source="/WpfApplication4;component/Images/LargeIcon.png"
                                   Margin="5" />
                            <TextBlock DockPanel.Dock="Top" Text="Label1" />
                            <TextBlock DockPanel.Dock="Top" Text="Label2" />
                        </DockPanel>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>
    </Application.Resources>
</Application>

utilisé .xaml

<CheckBox Style="{StaticResource ResourceKey=MyCheckBox}" />  

Quelque chose d'être présenté, mais la petite grille est disparu, comme ceci:

Comment puis-je faire?
