Thank you for your question.
You can take a look at our Examples application that you can find in the installation folder of UI for Windows Phone 8
which by default is: C:\Program Files (x86)\Telerik\UI for Windows Phone 8 QX XXXX
. Please, see the FirstLook example for the Calendar control where RadDataBoundListBox control is used to display the appointments in the selected calendar cell. You can use the RadDataBoundListBox.SelectionChanged event to see which appointment has been selected from the list.
I hope this helps.
