You guys rock and I love your controls. One of your strong points is that you keep as close to the microsoft controls as possible.
Is it possible that you can just expose the DataItem in the Item property instead of the complex cast .
The difference in code is pretty big:
//Normal Repeater ItemDataBound
if (e.Item.DataItem is CustomProductDetail)
if ((((RadListViewDataItem)e.Item).DataItem is CustomProductDetail))
