Need help populating fields from database to form in page load

I am trying to populate the fields on a form from the database and the values aren't populating on the form. I have the value for the where clause hard coded in the code and it doesn't show the values that are in the database for that record on the form:

protectedvoid Page_Load(object sender, EventArgs e)
        {this.UnobtrusiveValidationMode = System.Web.UI.UnobtrusiveValidationMode.None;



            {
                labelRID.Text = Request.QueryString["id"];string rid = labelRID.Text;string activityid = labelactivityid.Text;if (!IsPostBack)
                {
                    Bindactivitycodedropdown();if (rid != "")
                    {

                        OracleConnection conn = new OracleConnection();
                        OracleCommand cmd = new OracleCommand();
                        conn.ConnectionString = strConnection;
                        conn.Open();

                        cmd.Connection = conn;
                        cmd.CommandText = "Select RID, BUYING_ACTIVITY_ID, CUSTOMER_SOURCE_CODE, CUSTOMER_NAME, CUSTOMER_CITY, CUSTOMER_STATE, CUSTOMER_POSTAL_CODE, BUYING_ACTIVITY_CODE from BUYING_ACTIVITY WHERE RID = '55555'";
                        cmd.Parameters.Add(new OracleParameter("RID", Request.QueryString["ID"]));
                        OracleDataAdapter da = new OracleDataAdapter(cmd);
                        cmd.CommandType = CommandType.Text;
                        OracleDataReader dr = cmd.ExecuteReader();if (dr.Read())
                        {
                            labelRID.Text = dr["rid"].ToString();
                            custname.Text = dr["customer_name"].ToString();
                            custcity.Text = dr["customer_city"].ToString();
                            custstate.Text = dr["customer_state"].ToString();
                            custpostalcode.Text = dr["customer_postal_code"].ToString();
                            activitycode.SelectedItem.Text = dr["buying_activity_code"].ToString();
                            custsrccode.Text = dr["customer_source_code"].ToString();
                            cvactivitycode.Enabled = false;//custname.Text = custstate.SelectedValue.ToString();//if (activitycode.SelectedValue == "0")//{//    custname.Text = "";//    custcity.Text = "";//    custpostalcode.Text = "";//}                            dr.Close();
                            conn.Close();
                        }else
                        {

                            labelRID.Text = "";
                            custname.Text = "";
                            custcity.Text = "";
                            custstate.Text = "";
                            custpostalcode.Text = "";
                            activitycode.SelectedItem.Text = "";
                            custsrccode.Text = "C812 - NASA";

                        }
                    }
                }
            }
        }
