Populating a ComboBox using C#

Define a class

public class Language
{
     public string Name { get; set; }
     public string Value { get; set; }
}

then...

//Build a list
var dataSource = new List<Language>();
dataSource.Add(new Language() { Name = "blah", Value = "blah" });
dataSource.Add(new Language() { Name = "blah", Value = "blah" });
dataSource.Add(new Language() { Name = "blah", Value = "blah" });

//Setup data binding
this.comboBox1.DataSource = dataSource;
this.comboBox1.DisplayMember = "Name";
this.comboBox1.ValueMember = "Value";

// make it readonly
this.comboBox1.DropDownStyle = ComboBoxStyle.DropDownList;

Create a class Language

public class Language
{
     public string Name{get;set;}
     public string Value{get;set;}
     public override string ToString() { return this.Name;}
}

Then, add as many language to the combobox that you want:

yourCombobox.Items.Add(new Language{Name="English",Value="En"});
