how can i cart items for shopping cart application ...i am really new to web development and i want to create a shopping cart and want to cart items in it. how should i cart items.
I am using an application from a book for a shopping application , to adapt for my own learning, but there seems to be a problem with the shopping cart page. This is a section I have not changed as there is no need to but there is an error. In the code behind the only thing new is the namespace:
namespace OIClothing { public partial class Cart : System.Web.UI.Page { ShoppingCart cart; // it doesn't like this, giving the debug message the type or namespace 'Shopping Cart" could not be found protected void Page_Load(object sender, EventArgs e) { CheckTimeStamps(); if (Session["cart"] == null) { cart = new ShoppingCart(); Session["cart"] = cart; } else { cart = (ShoppingCart)Session["cart"]; } GridView1.DataSource = cart.GetItems(); if (!IsPostBack) GridView1.DataBind(); btnCheckOut.Enabled = (cart.Count > 0); } protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e) { cart.DeleteItem(e.RowIndex); GridView1.DataBind(); }
but when running the page, this error is given: CS1061: 'ASP.cart_aspx' does not contain a definition for 'GridView1_RowDeleting' and no extension method 'GridView1_RowDeleting' accepting a first argument of type 'ASP.cart_aspx' could be found (are you missing a using directive or an assembly reference?)

I would like to know the usage of profile in shopping cart based sites.I could see from some of the cart websites that profile plays a major role for online shopping projects.It is better to know how this profile to create opnline website and which websites or example to reach the technologies as well.
Anyways i am having some serious trouble with a datalist. im sure it is probably pretty easy but im am just not very good at all with the codebehind. Basically i have a datalist connected to sqldatasource and it pulls a list of items. I want to be able to select a record from the datalist and store that value in some sort of shopping cart.
I have a listview displaying my products and an "Add to Cart" button in the item template. the button fires 2 functions that should add that specific products information and the order details to two SQL database tables(Orders and Quantity(intersection entity between Orders and Products tables)) then you get redirected to the shopping cart page and it should display the item(s) according the specific key in the Quantity table(key is foreign key in Orders)My problem is that i cannot pull any information from the specific item template when i click that button. Need a way to find that specific controls information in my listview. Can anyone help with this?Below is my item template...

We have a demand system where customer can demand the quantity they want for a particular deal.
For each demand they submit, a new record is added to the DealDemandRequest table with the CustomerID, DealID, Quantity
I want to be able to to calculate the total quantity demanded by a particular customer. Current I query the DealDemandRequest table for all the records by a particular customer and then do a sum of the Quanity column.
However, we are expecting this table to be over 1 million record and it is reallly really slow right now.. Any better ways?
I'm looking for a free shopping cart source code to start creating customized chart.MSC Musicstore sample code is too simple. NOPCommerce requires adding link into it in every page.Where so find such source code ?
Say i have a Laptop for 600.00. Say i change it to $650.00. How do shopping carts handle that? Like do they store the price in the cart or the item? How do they make sure they get the price they wanted but not bill the customer the new change without asking them? Or do most store them in both?
I was thinking maybe i could store it in both.So if the current price is over the cart price for a item, don't remove it/bill them from their cart. Then after, tell them what was billed/email a receipt for the items that didn't change that was billed(say they had more then one item) and remove it from the cart. For the items that did change, say something like "Items left in cart due to price change, check if you still want to buy the items at the new price." So leave the items that changed in the cart but update the price in the cart.
I don't think the language should matter. Guess this is more of a logical type question. Do most shopping carts do it this way or is there a better way?
