如何做网站商铺甪直做网站

绑定后,原list值变动,显示内容会刷新

绑定后,list新添加的值时不会显示到界面,需要重新绑定list

微软的Bug

参考代码

        public class Student{public string Name { get; set; }}List<Student> list = new List<Student>();private void Form2_Load(object sender, EventArgs e){list.Add(new Student() { Name = "张三" });list.Add(new Student() { Name = "李四" });this.dataGridView1.DataSource= new BindingList<Student>(list);}private void button1_Click(object sender, EventArgs e){//注意  新添加的数据是无法展示到dgv里面的!!!list.Add(new Student() { Name = "王五" });list.Add(new Student() { Name = "赵六" });dataGridView1.Refresh();}private void button2_Click(object sender, EventArgs e){//元素删除list.RemoveAt(0);dataGridView1.Refresh();}private void button3_Click(object sender, EventArgs e){//元素修改list[0].Name=DateTime.Now.ToString();dataGridView1.Refresh();}private void button4_Click(object sender, EventArgs e){//重新绑定if (list.Count!=dataGridView1.Rows.Count){this.dataGridView1.DataSource=null;this.dataGridView1.DataSource= new BindingList<Student>(list);}
else{dataGridView1.Refresh();}}
