C＃DataGridView更新单元格值

Question

I write code in C# that show value of List in DataGridView:

I have this list:

List<Order> list = new List<Order> { new Order("Fettina ai Ferri", ""), new Order("1 X", "0.99") };

this list shows in datagridview (ordersDtaGrid):

var source = new BindingSource();
source.DataSource = list;
ordersDtaGrid.DataSource = source;

It works.

Now i change a value in list:

list[1].name = "4 X"

And i would like to update datagrid:

var source = new BindingSource();
source.DataSource = list;
ordersDtaGrid.DataSource = source;

And this is result in datagrid:

There are both the old and the new value.

I have also try adding:

ordersDtaGrid.Refresh();
ordersDtaGrid.Focus();

but nothig.

How can i fix this.

Thank you.
