Check this code if i understand exactly what you need then this will work for you.

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        SAN();
        bind();


    }
}

private void bind()
{
    ArrayList ar = new ArrayList();
    ar.Add("first");
    ar.Add("Second");
    ar.Add("Third");
    ar.Add("Four");
    ar.Add("Five");
    ar.Add("Six");
    ar.Add("Seven");
    DropDownList1.DataSource = ar;
    DropDownList1.DataBind();
    DropDownList1.SelectedValue = Session["Sitealiasname"].ToString();
}

public void SAN()
    {
        cn.Open();
        string sq = "select  Sitealiasname from tbl_Sitemaster where sitename in (select sitename from tbl_emploeedetails where employeestatus='L' and employeeid='" + Session["EMPID"].ToString() + "') and    status='A' order by Sitealiasname asc";
        SqlCommand d = new SqlCommand(sq, cn);
        SqlDataReader r;
        r = d.ExecuteReader();
        while (r.Read())
        {
            Label4.Text = r["Sitealiasname"].ToString().Trim();
            Session["Sitealiasname"] = Label4.Text;//Suppose here session value "first"
        }

        cn.Close();

    }

let me know if not what you want.
