WPF将DataGridCheckBoxColumn更改为Red Dots

Question

我想在数据网格的DataGridCheckBoxColumn中将复选框更改为红点。因此，选中的项目为红点，未选中的项目为空。如何更改DataGridCheckBoxColumn中的样式？

尝试这一点，它是根据stackoverflow.com/questions/1345961/在之前的评论中提到的Ansel Faillace改编的。

<DataGrid x:Name="dataGrid" Margin="10" ItemsSource="{Binding}">
    <DataGrid.Resources>
        <Style x:Key="GreenRedCheckBox" TargetType="{x:Type Checkbox}">
            <Setter Property="HorizontalAlignment" Value="Center />
            <Setter Property="VerticalAlignment" Value="Top" />
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="{x:Type ToggleButton}">
                        <Border x:Name="innerBorder">
                            <Ellipse x:Name="statusLight"
                                     Fill="Red"
                                     Stretch="Fill"
                                     Stroke="Black"
                                     HorizontalAlignment="Center"
                                     VerticalAlignment="Center"
                                     Height="10"
                                     Width="10" />
                        </Border>
                        <Trigger Property="IsChecked" Value="True">
                            <Setter Property="Fill" TargetName="statusLight" Value="Green" />
                        </Trigger>
                        <Trigger Property="IsChecked" Value="False">
                            <Setter Property="Fill" TargetName="statusLight" Value="Red" />
                        </Trigger>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>
    </DataGrid.Resources>
    <DataGrid.Columns>
        <DataGrideCheckBoxColumn ElementStyle="{StaticResource GreenRedCheckBox}"
                                 EditingElementStyle="{StaticResource GreenRedCheckBox}" />
    </DataGrid.Columns>
</DataGrid>
