How to populate 'select' from a database in asp.net

I have an html control select

 <select id="Select1" runat="server" name="D1">
    <option></option>
 </select>

How can I populate it with data from my database SQL Serverusing C#or JavaScript/jQuery/JSON?

Please do not post answers to the question about how to fill in asp:DropDownList, because I already know how to do this, I have to use the control select.

function GetItems() {

var items;

    $.getJSON("/api/MethodName/" + id(Optional), function (data) {
        $.each(data, function (key, val) {
            items += "<option value='" + val.id+ "'>" + val.value+ "</option>";    
        });

        var header = '<option value=\'\'>Select...</option>';
        $('#Select1').html(header + items);
    });

};

You can use asp.net webapi for json, it is very easy and fast

:

 string options = string.Empty; 
 using (SqlConnection sql_conn = new SqlConnection(ConfigurationManager.ConnectionStrings["connstr"].ToString()))
        {
            SqlDataAdapter sql_adapter = new SqlDataAdapter("select Value, Name from YourTable", sql_conn);
            DataSet ds = new DataSet();
            sql_adapter.Fill(ds, "TempTable");

            foreach (DataRow row in ds.Tables["TempTable"].Rows)
            {
                options = "<option value='" + row["Value"] + "'>" + row["Name"] + "</option>";
            }
            sql_conn.Close();
           return options;
        }

jquery:

$.get(url, function (data) {        
        $('#Select1').html(data);
    });

Aspx:

  <select id="Select1" runat="server" name="D1">

  </select>

code behind:

protected void Page_Load(object sender, EventArgs e)
{
   if (!IsPostBack)
   {
      string ConnectString = "server=localhost;database=pubs;integrated security=SSPI";
      string QueryString = "select * from authors";

      SqlConnection myConnection = new SqlConnection(ConnectString);
      SqlDataAdapter myCommand = new SqlDataAdapter(QueryString, myConnection);
      DataSet ds = new DataSet();
      myCommand.Fill(ds, "Authors");

      Select1.DataSource = ds;
      Select1.DataTextField = "au_fname";
      Select1.DataValueField = "au_fname";
      Select1.DataBind();
   }
}
