Thank you for your question.
When the looping list from the slot machine experience example starts spinning its SelectedIndex changes to -1, when it stops, the SelectedIndex is changed to the index of the selected item. You can use the SelectedIndexChanged event to observe these changes. Once you have the selected index, you can use it to get the item from the LoopingListDataSource by using the method GetItemAt. Then you can easily obtain any information that you need from that item after you cast it to the correct type. Here's how and event handler could look to display the Uri of the selected picture in the first look example:
sender, EventArgs e)
(selectedIndex != -1)
PictureDataItem selectedItem =
"You selected "
