Read data into list like
class country
{
public string id{get; set;}
public string name{get; set;}
}
for DB we will access names and code push thos values into a list
List<country> l=new List<country>();
country c=null;
c=new country();
c.id="1";
c.name="india";
l.add(c);
c=new country();
c.id="2";
c.name="srilanka";
l.add(c);</country></country>
where you are writing drop down use like this
<![CDATA[<%foreach(country c in l)
{%>]]>
<a href="<%=c.id%>">,%=c.name%></a>
<![CDATA[<%}%>]]>
