Putting a datatable into the session seems wasteful to me.

Does this work ? In C# it would miss the last item.

Every time ? Why on earth are you doing this inside the loop ?

DataList1.DataSource = dt DataList1.DataBind()
Wow - again, this is very wasteful.

There's much better ways to do this. How about storing an id in the session and storing the cart in the database ? Then you could modify the cart with SQL, for a start.

What are you writing this for ? Is it actually going to be used for anything ? By whom ?
