I appreciate you taking the time to help.
I am struggleing I think to find relevent documentation. I am using the following code below to add special days in.
I am calling this in the dayrender event but it seems to be inconsistent. For example using the code below the tooltip is not showing up where as if I set the e.Cell.ToolTip property it does show up. Also styles are differently applied (ie. the style assignment only shows up on a rollover)
Very confusing and there seem to be very few "real world" examples available.
bookedDay = new RadCalendarDay(RadCalendar1);
new DateTime(e.Day.Date.Year, e.Day.Date.Month, e.Day.Date.Day);
// repeat day only once
bookedDay.Repeatable = Telerik.Web.UI.Calendar.
// add to special days list
