If there is no more oldValue, I will have to come up with a new technique. The current technique checks the difference in quantity and adjusts the item price and the footer subtotal and total by that amount. This is a shopping cart checkout page (see it live at http://www.blowitoutahere.com
- pre-kendo version - stick on ?debugjs=on to see uncompressed scripts).
A solution will be to iterate thru all items to recalculate and update the subtotals and totals.
Is there a way to modify the cart grid data instead of modifying the table cell contents and then tell the grid to re-generate using the changed data? This is a server-side Telerik grid, not Kendo (yet) and but scollable so all the data is available (there can be 100's of items in the cart).
