How to use one List for two comboboxes?

Question

.NET

There is combobox1 and combobox2. There is a list.
list = List<objects>
combobox1 and combobox2 contain the same values ​​(list):

combobox1.DataSource = list;
combobox2.DataSource = list;

When I change the value in combobox1, it also changes in combobox2 (and vice versa).
How to make selected combobox values ​​independent?

Answer 1

comboBox1.DataSource = new BindingSource() {DataSource = list};
comboBox2.DataSource = new BindingSource() {DataSource = list};
