Q:

How to increase the quantity using Shopping cart Content webpart

I need feature in checkout page where used should be able to increase/decrease/delete the cart items. I used ShoppingCartContent webpart for this. There is a text box to change the number of quantity but what happens next? how the price and quantity get updated. I can't see any button or controls which update the price or quantity in the cart. Please let me know if you have any inputs on this.
Thanks, Sharath

A:

You should have a control called CartItemUnits inside your transformation
(ecommercesite.transformations.checkoutshoppingcartitem):
<%@ Register Src="~/CMSModules/Ecommerce/Controls/Checkout/CartItemUnits.ascx" TagName="CartItemUnits" TagPrefix="cms" %>

<cms:CartItemUnits runat="server" CartItemID='<%# Eval("CartItemID")%>' UnitFormControlName="TextBoxControl" ShowUpdate="true" ImageURL="~/App_Themes/EcommerceSite/Images/Ecommerce/checkout_refresh.png"  ControlType="image" />

This CartItemsUnites  has ControlType property that can be image or button, I suggest switch to button i.e. ControlType="button" You probably missing the "refresh" image and make sure you have ShowUpdate="true" i.e.:
<cms:CartItemUnits runat="server" CartItemID='<%# Eval("CartItemID")%>' UnitFormControlName="TextBoxControl" ShowUpdate="true"  ControlType="button" />

It should give text box with #of units and update button nex to it
