在WPF中，是否可以在keyup事件上强制更新datagrid？

public class MyViewModel : INotifyPropertyChanged
{
    public ICommand UpdateDataCommand { get; set; }

    private ObservableCollection<MyData> _dataList;
    public ObservableCollection<MyData> DataList
    {
        get { return _dataList; }
        set
        {
            _dataList = value;
            OnPropertyChanged(nameof(DataList));
        }
    }

    public MyViewModel()
    {
        UpdateDataCommand = new RelayCommand(UpdateData);
        DataList = new ObservableCollection<MyData>();
    }

    private void UpdateData()
    {
        // 更新数据源
        DataList.Add(new MyData { Name = "John", Age = 25 });
        DataList.Add(new MyData { Name = "Jane", Age = 30 });
        // 强制刷新datagrid
        CollectionViewSource.GetDefaultView(DataList).Refresh();
    }

    // INotifyPropertyChanged接口实现代码省略...
}
