C# 2 ComboBox DropDownList Showing Same Values?

In my code I have 2 ComboBox DropDownLists, created by the code below. The problem is that when the value of the DropDownlist get changed, the other one value also changes.

public class Translate
{
public string CountryName { get; set; }
public string CountryCode { get; set; }
}
IList<Translate> languages = new List<Translate>();
languages.Add(new Translate("Select", ""));
languages.Add(new Translate("English", "en"));
languages.Add(new Translate("French", "fr"));
languages.Add(new Translate("Spain", "es"));
ddlFrom.DataSource = languages;
ddlFrom.DisplayMember = "CountryName";
ddlFrom.ValueMember = "CountryCode";
ddlTo.DataSource = languages;
ddlTo.DisplayMember = "CountryName";
ddlTo.ValueMember = "CountryCode";
