I need to create the shopping cart in .Net 3.5 with below features. I am using 4 tier architecture Presentation, Business entity, BAL and DAL.
1) Full catalog display including Item name, description, Image, different Options for spending like Points only , Points + dollar value. For this page i have one BO and collection class which returns collection list of objects to presentation layer and bind the same to Grid view. Problem here is that each object in collection list includes another collection list of spending options(retrieved from another table on the basis of item id). So i got stuck how to bind 2 collection list with grid view. What is the best method in .Net to display items having multiple spending options for each item.
2) Item details page display
3) Shopping cart page including features of
a) Updating quantity in batch
b) Removing items added in cart (individual/Batch)
4) Check out to payment gateway.
I am new in .Net. Please help to share some freeware source code/Tutorials which will fulfill above requirement
