我试图将observable集合绑定到DataGrid,我想在datagrid中编辑任何行时通知.我的代码适用于添加或删除记录时的通知,但是在编辑记录时没有通知.如果这是使用MVVM中的可观察集合进行绑定的正确方法,请告诉我,以及我是否缺少某些内容.提前致谢.

public class studentViewModel : INotifyPropertyChanged

    public studentViewModel()
    {
        _student = new studentModel();
        myCollection = new ObservableCollection<studentModel>();

        System.Windows.MessageBox.Show(e.Action.ToString());
    }

    ObservableCollection<studentModel> _myCollection;

        set
        {
            if (_myCollection != value)
            {
                _myCollection = value;
                raisePropertyChange("myCollection");
            }
        }
    }

    public int rollNo
