wpf - DataGridTextColumn值更改时如何更改DataGridCheckBoxColumn值？

Question

我正在将wpf与mvvm一起使用，并且我有一个4列的datagrid:
ID，原始，已翻译，已翻译
我想当“翻译”列中的文本更改时，“IsTranslated”列的值自动更改为选中
这是我的datagrid xaml代码:

<DataGrid Grid.Row="3" AutoGenerateColumns="False" ItemsSource="{Binding AllXliffs}">
            <DataGrid.Columns>
                <DataGridTextColumn Header="ID" Binding="{Binding Path=Id}" />
                <DataGridTextColumn Header="Original" Binding="{Binding Path=Original}" />
                <DataGridTextColumn Header="Translated" Binding="{Binding Path=Translated}" />
                <DataGridCheckBoxColumn Header="IsTranslated"  Binding="{Binding Path=IsTranslated, Mode=TwoWay, Converter={StaticResource StringToBooleanConverter}, UpdateSourceTrigger=PropertyChanged}" ></DataGridCheckBoxColumn>
            </DataGrid.Columns>
</DataGrid>

由于您正在使用MVVM，因此可以在model属性中添加小型业务逻辑:

像这样 :

        private string _translation;
        private bool _isTranslated;

        public string Translation
        {
            get { return _translation; }
            set
            {
                _translation = value;
                IsTranslated = !String.IsNullOrEmpty(_translation);
            }
        }

        public bool IsTranslated
        {
            get { return _isTranslated; }
            set
            {
                _isTranslated = value;
                OnPropertyChanged("IsTranslated");
            }
        }
