    public string lists = null;
    protected void Page_Load(object sender, EventArgs e)
    {
        lists = null;
        lists = BindName();
    }
    private string BindName()
    {
        DataTable dt = null;
        using (conn = new SqlConnection(ConfigurationManager.ConnectionStrings["cnn"].ConnectionString))
        {
            using (SqlCommand cmd = conn.CreateCommand())
            {
                cmd.CommandType = CommandType.Text;
                cmd.CommandText = "select CountryName from Country";
                using (SqlDataAdapter da = new SqlDataAdapter(cmd))
                {
                    dt = new DataTable();
                    da.Fill(dt);
                }
            }
        }
     
        StringBuilder output = new StringBuilder();
        output.Append("[");
        for (int i = 0; i < dt.Rows.Count; ++i)
        {
            output.Append("\"" + dt.Rows[i]["CountryName"].ToString() + "\"");

            if (i != (dt.Rows.Count - 1))
            {
                output.Append(",");
            }
        }
        output.Append("];");  
        return output.ToString();
    }
