Thank you for contacting us.
1) We are aware of this issue and it will be fixed with our Q2 release which is scheduled for the middle of July this year. I am attaching a fixed version of the FirstLook example.
2) Yes, you can put whichever visual element you like as content to RadTileViewItem, since the Content property of RadTileViewItem is of type object
3) You are correct that the course ware document does not contain information about RadTileView. However, I'd recommend you go through RadTileView's help page
as it explains most of its features. You can always contact us through a forum post or support ticket whenever you have a question.
Let me know if I can be of further assistance.
