I used 3 ddl for address purpose using ajax extention (script manager and update panel)
they worked but when user never select any country,state or city and submit then header for each ddl (select country,select city,select state) stored in database.

Accepted answer
then You have to validate it before inserting to database.

Ex:
    within insert button click event write below code
if(ddlCountry.SelectedIndex==0)
        {
        lblmsg.text="select country";
        return;
        }
if(ddlCity.SelectedIndex==0)
        {
        lblmsg.text="select city";
        return;
        }
if(ddlstate.SelectedIndex==0)
        {
        lblmsg.text="select state";
        return;
        }
after this code insert data to database.

you can also use javascript

no no no.....my question are how to prevent storing "Select Country","Select State" or "Select City" text(that are used for header purpose) when user never select a country,state or city.

In page load bind the dropdown by checking postback

ex-

if (!IsPostBack)
        {
            Bind(); //or your dropdown bindcode
        }
