Thanks Juraj,I followed the steps in the article while using the sample Corporate Site.
It already has the ecommerce piece setup.
I modified the EventRegisitrationDetail (Event (booking system) transformation to include the following, my only issue is that when I click add to cart, nothing happens.
<uc1:CartItemSelector id="cartItemSelector" runat="server" SKUID='<%# ValidationHelper.GetInteger(Eval("SKUID"), 0) %> ' SKUEnabled=' <%# ValidationHelper.GetBoolean(Eval("SKUEnabled"), true) %> ' AddToCartImageButton="addtocart.gif" AddToCartLinkText="Add to shopping cart" />
I am trying to implement this as a proof of concept that our company can use Kentico for promoting paid events.
