MiniCart Web Part
The Mini Cart Web Part applies an XSLT template to render a short summary of the shopping cart, including line item count and subtotals.
Architecture
The Mini Cart Web Part contains these components:
MiniCartWebPart/SPMiniCartWebPart: applies the XSLT template to render the Mini Cart Web Part HTML code. This component uses the SiteContext class to read and write the subtotal and line items count to the session (which uses an HTTP cookie). If the session does not contain this information, the ShoppingController is called to retrieve the basket. The XML source is a root node called "Basket". The subtotal and line items are passed into the XSLT as arguments.
ShoppingController: encapsulates all multi-channel commerce foundation calls relating to putting items in a cart and checkout-related operations. When a basket is loaded or retrieved, the ShoppingController class updates the subtotal and line item count in the session.
