Question

I’m creating a shopping basket in ASP.NET using session variables to pass the data from a shopping.aspx page to basket.aspx, currently I have the pages passing the primary key of the product with a gridview on the basket.aspx used to display the data from the database.

However this only works for one item at a time, how can I extended the session variable so multiple products can be added, as well as quantities etc?

Answer 1

You can use your own object, eg. Basket which can have one or more properties.

Object should be market as Serializable.

For example:

[Serializable]
public class Basket
{
    public List<BasketItem> Items {get;set;}
    public int UserId {get;set;}
}

[Serializable]
public class BasketItem
{
    //...
}
