Unfortunately there is no such built in functionality in RadCalendar. If I understand you correctly you are trying to modify the First Look example
of the RadCalendar in order to create a custom tooltip for the dates which are containing events. Basically you could achieve this by creating a MultiValueConverter
which should returns the value of the tooltip. I've modified the First Look example in order to meet the requirements. You could find attached the modified example.
Hope this helps.
