WPF將DataGridCheckBoxColumn更改爲紅點

Question

我想在數據網格的DataGridCheckBoxColumn中將我的複選框更改爲紅點。所以檢查的項目是紅點，而未檢查的項目是空的。我如何更改DataGridCheckBoxColumn中的樣式？

試試這個，它是從stackoverflow.com/questions/1345961/改編而來，它在之前的評論中被Ansel Faillace提及。

<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>
