Hi,

From http://forums.asp.net/t/1243553.aspx article, im using ShoppingCart.cs to implement ShoppingCart class.

Im also trying below code

----------------------------

protected void Button1_Click(object sender, EventArgs e)
{
    ShoppingCart cart = new ShoppingCart();
    cart.ProductID = 1;
    cart.ProductName = ListBox1.SelectedItem.Value;
    cart.ProductDescription = "Some Description";
    cart.Quantity = Convert.ToInt32(TextBox1.Text);
    cart.Size = DropDownList1.SelectedItem.Value;
    cart.Color = DropDownList2.SelectedItem.Value;

    if (cart.ProductName == "Sweaters" && cart.Size == "XX-Large")
        cart.Price = 29.95M;
    else
        cart.Price = 19.95M;

    Session["Order"] = cart;

    Response.Redirect("~/OrderDetails.aspx");
}

----------------------------

From my understanding, Session["Order"]  holds 1 object (1 product) at that moment. Still thinking how this class can holds more than 1 product?

Im really stuck, how to using same class to assign another value but the im still can call the previous value that i've assigned. So, i can have View Cart in my application with more than 1 product.

Really need techinical explanation.

 Hi

This will help u lot if u have query plz let me know Dont forget that u must use genrices list for product so u can have n number of product in a single session

Cart should be Structured like as given below

CART 

public class Cart
{

        public List<Products> Products = new List<Products>();
        public float TotalAmt;
        public float TotalWeight;
        public float ShippingCharge;
        public float Tax;
        public float TotalSum;
        public int ShippingAddress;
        public float SubTotal;
        public float PaymentAmount;
}

PRODUCT

public class Products
    {
        private int _ProductId;
        private string _ProductName;
        private string _ShortDescription;
        private string _LongDescription;
       // List of Property
        #region "Price attached for display in ProductLarge Page"
           
        private float _Price;
        private int _Quantity;

        public int Quantity
        {
            get { return _Quantity; }
            set { _Quantity = value; }
        }
           

        public float Price
        {
            get { return _Price; }
            set { _Price = value; }
        }
        #endregion

        public int ProductId
        {
            get { return _ProductId; }
            set { _ProductId = value; }
        }

        public string ProductName
        {
            get { return _ProductName; }
            set { _ProductName = value; }
        }
       
        public string ShortDescription
        {
            get { return _ShortDescription; }
            set { _ShortDescription = value; }
        }

        public string LongDescription
        {
            get { return _LongDescription; }
            set { _LongDescription = value; }
        }

     }

POPULATING

Session["Carts"] =(Cart)Session["Cart"];

  if (Session["Carts"] != null)
                        {
                           
              
                            objCart.TotalAmt = 0;
                            foreach (Products objProducts in objCart.Products)
                            {
                                objCart.TotalAmt += objProducts.Price * objProducts.Quantity;
                            }
                            string l_subtotal = string.Format("{0:f}", objCart.TotalAmt);
                            ltrSubTotal.Text = l_subtotal;
                            if (objCart.Products.Count != 0)
                            {
                                gvShoppingCart.DataSource = objCart.Products;
                                gvShoppingCart.DataBind();
                              
                            }
                          
                        }

objCart.TotalAmt = 0;

I dont understand this part. where objCart.TotalAmt = 0; come from? No need to declare?

it s declared in cart class and i had declared since at the beginning it should be 0 so that when i itreate the products i can get total amount based on the products price

check that objcart.totalamt+= where it will be incremented so i used this steps

tq for the explaination.

im interested when you said, Dont forget that u must use genrices list for product so u can have n number of product in a single session

Do u have any sample, how to play around with this generic list. The most important thing, in terms of how to add,remove and update this generic list.

Need your advice.

Hi Dude,

   }
                x++;
            }

                    }
                    if (!ProductAlreadyExist)
                    {
                        objProducts.Quantity = 1;
                        objCart.Products.Add(objProducts);
                    }
                }
                if (Session["User"] != null)
                {
                    Response.Redirect("shoppingcart.aspx");
                }
                else
                {
                    Response.Redirect("login.aspx");
                }
