First of all thank you for such a superb book! I have learned so much from this.

I am struggling with what I thought would be a simple modification which I trust you can help with. I think that I am missing something inherently simple.

I am using the skeleton from The instant results book as a basis for my project. Rather than a web shop it is a scenario where users select items from the database always in a quantity of 1 item and with no fixed price. I need to allow clients to be able to input their own prices during the shopping cart session or at the checkout stage.

I thought this would be an easy thing to implement but I'm stuck!!

Any help would be VERY welcome! As I am a bear of very little brain.

Many thanks in advance:)

Hi Malex,

Here's what I would do from a high level overview:

1. Change the OrderedProduct class by renaming the Quantity property to Price, or something like that. Make sure you change all underlying fields in the database and stored procedures as well. You may also need to change the type from an Int to a double.

2. In the ShoppingCart, change the DropDownList to a TextBox

3. Within the Update code, get a reference to the new TextBox, get the price and then update the Price property, similar to how it's done now with the quantity.

4. Replace all references to Quantity with Price in the ASPX pages (databinding, update code and so on).

If there are specific questions you need help with, let me know...

Cheers,

Imar
