If you simply want to add it without creating a new class try this:

// WPF
<ComboBox Name="language" Loaded="language_Loaded" /> 


// C# code
private void language_Loaded(object sender, RoutedEventArgs e)
{
    List<String> language= new List<string>();
    language.Add("English");
    language.Add("Spanish");
    language.Add("ect"); 
    this.chartReviewComboxBox.ItemsSource = language;
}

I suggest an xml file with all your languages that you will support that way you do not have to be dependent on c# I would definitly create a class for languge like the above programmer suggest.

What you could do is create a new class  similar to  Gregoire s example  however  you would want to override the ToString   method so it appears correctly in the combo box e g   public class Language       private string  name      private string  code       public Language string name  string code                 name   name           code   code             public string Name   get   return  name           public string Code   get   return  code          public override void ToString                 return  name

Language   items   new Language   new Language  English    En                    new Language  Italian    It                  languagesCombo ValueMember    Alias               languagesCombo DisplayMember    FullName               languagesCombo DataSource   items ToList                 languagesCombo DropDownStyle   ComboBoxStyle DropDownList    class Language               public string FullName   get  set            public string Alias   get  set             public Language string fullName  string alias                        this FullName   fullName              this Alias   alias                    By making your drop down box  read-only  I am assuming you want to prevent user s typing in other options as opposed to being fully read-only where users cannot select a value    If you wanted it to be fully read-only you could set the enabled property to be false

To make it read-only  the DropDownStyle property to DropDownStyle DropDownList   To populate the ComboBox  you will need to have a object like Language or so containing both for instance   public class Language       public string Name   get  set        public string Code   get  set        Then  you may bind a IList to your ComboBox DataSource property like so   IList lt Language gt  languages   new List lt Language gt     languages Add new Language  English    en     languages Add new Language  French    fr      ComboxBox DataSource   languages  ComboBox DisplayMember    Name   ComboBox ValueMember    Code     This will do exactly what you expect
