Use class or one method to bind three cascading DDL

Question

Hi

I trying my best to make my web application faster as much as i can, so one of what i am looking is reducing the codes into each page. So i have three DDL as mention below they do the same job to bind the DDL's depending on cookie value. So how i can create a class and use it for to bind all DDL's or i dont know if it possible to bind three of those DDLs into one method as below method as they are doing the same job?

-StateHPDDL

-BizstateHPFilterDDL

-filterstathpjob

the code used for each DDL in page_load is as below

if (!IsPostBack)
            {
                if (cookie["Location"] == null)
                {

                    DataTable filterstathpAdsDT = new DataTable();

                    using (SqlConnection filterstathpAdsCon = new SqlConnection(cs))
                    {

                        SqlCommand filterstathpAdsCMD = new SqlCommand("SELECT State FROM State WHERE Country = @Location", filterstathpAdsCon);

                        var Location = cookie.Value;

                        filterstathpAdsCMD.Parameters.AddWithValue("@Location", Location);


                        SqlDataAdapter filterstathpAdsAP = new SqlDataAdapter();
                        filterstathpAdsAP.SelectCommand = filterstathpAdsCMD;
                        filterstathpAdsAP.Fill(filterstathpAdsDT);

                        StateHPDDL.DataSource = filterstathpAdsDT;
                        StateHPDDL.DataTextField = "State";

                        StateHPDDL.DataBind();
                    }

                    StateHPDDL.Items.Insert(0, new ListItem("Select Province", ""));
                }


            }
