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();}
- }
