c# - 未触发DataGrid上复选框的未选中事件

Question

我已处理事件以检查/未检查数据网格上的复选框

        <DataGridCheckBoxColumn Header="Emp Acknowlegement" Binding="{Binding Path=Trained}" Width="*">
            <DataGridCheckBoxColumn.ElementStyle>
                <Style TargetType="CheckBox">
                    <Setter Property="IsEnabled" Value="False"/>
                    <EventSetter Event="Checked" Handler="empAck_OnCheck"/>
                    <EventSetter Event="Unchecked" Handler="empAck_OnUncheck"/>
                    <Style.Triggers>
                        <DataTrigger Binding="{Binding isUser}" Value="1">
                            <Setter Property="IsEnabled" Value="True" />
                        </DataTrigger>
                    </Style.Triggers>
                </Style>
            </DataGridCheckBoxColumn.ElementStyle>
        </DataGridCheckBoxColumn>
        <DataGridCheckBoxColumn Header="Effectiveness Check" Binding="{Binding Path=EffectiveCheck}" Width="*">
            <DataGridCheckBoxColumn.ElementStyle>
                <Style TargetType="CheckBox">
                    <Setter Property="IsEnabled" Value="False"/>
                    <EventSetter Event="Checked" Handler="effAck_OnCheck"/>
                    <EventSetter Event="Unchecked" Handler="effAck_OnUncheck"/>
                    <Style.Triggers>
                        <DataTrigger Binding="{Binding Level}" Value="2">
                            <Setter Property="IsEnabled" Value="True" />
                        </DataTrigger>
                    </Style.Triggers>
                </Style>
            </DataGridCheckBoxColumn.ElementStyle>
        </DataGridCheckBoxColumn>

该复选框将触发两个事件。第一个仅触发Checked事件。我将处理程序交换为“已检查”和“未检查”，以查看是否是导致问题的未检查方法，但它运行正确。看来该事件没有触发。第二个框的代码相同，但是会按预期触发。

    private void empAck_OnCheck(object sender, RoutedEventArgs e)
    {
        MessageBox.Show("Checked");

    }

    public void empAck_OnUncheck(object sender, RoutedEventArgs e)
    {
        MessageBox.Show("Unchecked");

    }

尝试另一种方法

//It's not answer to question but it will work to resolve it

//USE click event for both, add code
<EventSetter Event="Clicked" Handler="empAck_OnClicked"/> 

//add event as
public void empAck_OnClicked(object sender, RoutedEventArgs e)
{
  CheckBox c=(CheckBox) sender;
  if(c.IsChecked==true)
  {

  }
  if(c.IsChecked==false)
  {

  }
}
