Answer 1

you need to use the SortableBindingList class:

 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;
