This shows how to bind Country names in DropDownList & also it contains some advantages.


<html xmlns="">
<head   runat="server">
    <title>Bind Country names in Dropdownlist</title>
    <form id="form1"   runat="server">
        <asp:DropDownList ID="ddlLocation" runat="server">        

using System;
using System.Collections.Generic;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Globalization;
using System.Collections;
using System.Text;

public partial class _Default : System.Web.UI.Page 
    protected void Page_Load(object sender, EventArgs e)
        ddlLocation.DataSource = CountryList();
        ddlLocation.DataTextField = "Key";
        ddlLocation.DataValueField = "Value";

    public SortedList CountryList()
        SortedList slCountry = new SortedList();
        string Key = "";
        string Value = "";

        foreach (CultureInfo info in CultureInfo.GetCultures(CultureTypes.SpecificCultures))
            RegionInfo info2 = new RegionInfo(info.LCID);
            if (!slCountry.Contains(info2.EnglishName))
                Value = info2.TwoLetterISORegionName;
                Key = info2.EnglishName;
                slCountry.Add(Key, Value);
        return slCountry;


  • Here, Country names are loading from code behind so we can apply some filter/restriction for the items list here.(Example: Loading European countries, Loading Country names starts with 'A', etc.,)

  • Here TwoLetterISORegionName is used to DataValueField for DropDownList but we can use other things such as ThreeLetterISORegionName, NativeName, ISOCurrencySymbol, GeoId, CurrencySymbol, etc., from RegionInfo class

  • We can sort the Key field because SortedList was used here
