当使用BindingList和BindingSource在切线中实现INotifyPropertyChanged时，如下所示，无需触摸DataGridView，添加或编辑的数据将显示而不需要刷新。
在下面的例子中，所有的事情都在表单中完成，而对于代码，你需要进行调整。比如我如何加载数据。

using System.ComponentModel;
using System.Runtime.CompilerServices;

namespace WinFormsApp1;
public partial class NoRefreshForm : Form
{
    private BindingList<StudentModel> _students;
    private BindingSource _source = new BindingSource();
    public NoRefreshForm()
    {
        InitializeComponent();
        Shown += OnShown;
    }

    private void OnShown(object sender, EventArgs e)
    {
        // add several students
        List<StudentModel> students = new List<StudentModel>
        {
            new StudentModel() { FirstName = "Anne", LastName = "Jones" },
            new StudentModel() { FirstName = "Jim", LastName = "Adams" }
        };

        _students = new BindingList<StudentModel>(students);
        _source.DataSource = students;
        dataGridView1.DataSource = _source;
    }

    private void AddButton_Click(object sender, EventArgs e)
    {
        // add a new student, will show up in the DataGridView
        _source.Add(new StudentModel() { FirstName = "Mike", LastName = "Smith" });
    }

    private void EditCurrentButton_Click(object sender, EventArgs e)
    {
        // get current student from DataGridView current row
        StudentModel student = _students[_source.Position];
        // update properties
        student.FirstName = student.FirstName + "!";
        student.LastName = student.LastName + "@";
    }
}

// class belongs in its only file
// INotifyPropertyChanged - Notifies clients that a property value has changed.
public class StudentModel : INotifyPropertyChanged
{
    private string _firstName;
    private string _lastName;

    public string FirstName
    {
        get => _firstName;
        set
        {
            if (value == _firstName) return;
            _firstName = value;
            OnPropertyChanged();
        }
    }

    public string LastName
    {
        get => _lastName;
        set
        {
            if (value == _lastName) return;
            _lastName = value;
            OnPropertyChanged();
        }
    }

    public event PropertyChangedEventHandler PropertyChanged;
    protected virtual void OnPropertyChanged([CallerMemberName] string propertyName = null)
    {
        PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
    }
}
