It still not clear for me if you are trying to replace the current RadListView
control to display the product list, or if you just want to change the appearance of the populated list.
You can modify the template of the product list as shown in the following video
. However, since the appearance of the items is based on Sitefinity styles, I would recommend you to do the desired changes of the look and feel using styles too, in this case, sfproductListItem.
Do you want to have your say in the Sitefinity development roadmap? Do you want to know when a feature you requested is added or when a bug fixed? Explore the Telerik Public Issue Tracking
system and vote to affect the priority of the items
