Thank you for writing.
Even though thanks to our Telerik Presentation Framework
it is possible to add elements to RadPanorama's tiles, the control was not intended for this purpose and I cannot tell how the controls will behave when placed in RadPanorama.
For the sake of your question, I have created a small application (see attachment) demonstrating how to add RadListControlElement to RadTileElement. However, I will not recommend to add controls or elements to RadPanorama, since as I mentioned the control is not intended for this purpose and I cannot tell what behavior you will observe.
I hope that you find this information useful. Should you have any other questions, do not hesitate to contact us.
All the best,
the Telerik team
