推荐答案

如果使用自定义对象进行数据绑定，则意味着需要使用SortableBindingList.
这是示例.

If you are using your custom objects for databinding means you need to use the SortableBindingList.
Here is the example.

public Form1()
{
 InitializeComponent();
 
 SortableBindingList<person> persons = new SortableBindingList<person>();
 persons.Add(new Person(1, "timvw", new DateTime(1980, 04, 30)));
 persons.Add(new Person(2, "John Doe", DateTime.Now));
 
 this.dataGridView1.AutoGenerateColumns = false;
 this.ColumnId.DataPropertyName = "Id";
 this.ColumnName.DataPropertyName = "Name";
 this.ColumnBirthday.DataPropertyName = "Birthday";
 this.dataGridView1.DataSource = persons;
}</person></person>
