C# 布尔型DataGridComboxColumn显示是/否

我有一个与集合绑定的dataGrid。对于两列A和B，数据为1或0。 相反，我想在comboBoxColumn中显示Yes或No，当然，如果选择Yes，则保存1，选择No则保存0

我该怎么做

看法 视图模型 模型 使现代化 我试过这两种方法，但都不管用

我可以向你推荐这个问题的下一个确切解决方案。请看这个。 1.组合框XAML代码：

 <DataGridComboBoxColumn Header="ActivityStatus" SelectedItemBinding="{Binding IsActive, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}">
            <DataGridComboBoxColumn.ItemsSource>
                <x:Array Type="system:Boolean">
                    <system:Boolean>True</system:Boolean>
                    <system:Boolean>False</system:Boolean>
                </x:Array>
            </DataGridComboBoxColumn.ItemsSource>
        </DataGridComboBoxColumn>
