Hi
can any please complete the code below so that I can try and understand how to create a 3 tier web design.

 ============== Presention layer index.aspx==============================

<asp:FormView ID="frmCustomerDetails" Caption="Customer Details" runat="server">
    <ItemTemplate>
    <%# Eval("YourName") %>
    </ItemTemplate>
    </asp:FormView>

 ============== Code behind index.aspx.cs==============================

protected void Page_Load(object sender, EventArgs e)
        {
       
                try
            {
            FormsIdentity objLoginTicket;
            objLoginTicket = (FormsIdentity)User.Identity;
            IntReturnOrderNumber = Convert.ToInt32(objLoginTicket.Ticket.UserData);
            frmCustomerDetails.DataSource =
            frmCustomerDetails.DataBind()

I DO NOT KNOW HOW TO PASS THE VALUE OF IntReturnOrderNumber INTO THE BUSINESS LAYER

============== Business layer customerdetailsBL.cs ==============================

Not sure what goes here

============== Database layer customerdetailsDB.cs ==============================
public CustomerDetailsBL GetCustomerDetails(int IntReturnOrderNumber)
            {
            SqlConnection Conn = new SqlConnection(getdbConnection);
            SqlCommand Cmd = new SqlCommand("sp_xxxxx", Conn);
            Cmd.CommandType = CommandType.StoredProcedure;
            Cmd.Parameters.Add(new SqlParameter("@CustomerID", SqlDbType.Int, 4));
            Cmd.Parameters["@CustomerID"].Value = IntReturnOrderNumber;

            try
                {
                Conn.Open();
                SqlDataReader Rdr = Cmd.ExecuteReader(CommandBehavior.SingleRow);
                Rdr.Read();
                CustomerDetailsBL CustDtl = new CustomerDetailsBL(
                   (int)Rdr["OrderNumber"],
                    (string)Rdr["UserName"],
                     (string)Rdr["PassWord"],
                      (string)Rdr["YourName"],
                       (string)Rdr["JobTitle"],
                        (string)Rdr["CompanyName"],
                         (string)Rdr["CompanyAddress"],
                          (string)Rdr["CompanyCityTown"],
                           (string)Rdr["CompanyCountyState"],
                            (string)Rdr["CompanyPostCodeZipCode"],
                             (string)Rdr["CompanyCountry"],
                              (string)Rdr["CompanyPhone"]);
                Rdr.Close();
                return CustDtl;
                }
            catch (SqlException)
                {
                throw new ApplicationException("Sorry an error has occured");
                }
            finally
                {
                Conn.Close();
                Conn.Dispose();
                }
            }

Any help would be appreciated
George

I think you are little bit confuse with 3-tiers application.

Should do this:

1. Create seperate projects for each layer.
2. from Presention layer, create an object of bussiness layer
3. the class in bussiness layer process data and then create ao object of data access layer
4. class in data access layer insert data into database.

this is logic 3-tiers application.

However, we can also do phsical 3-tiers application as well - it is out of this topic.
