NewEnd property returns wrong date. Here with I explain you with example.
Suppose you are in the week view. Your event's start date is 10/15/2008 12:00 PMAnd EndDate is '10/17/2008 3:00 PM' Thus evant span across multiple days. DayPilot calendar displays it properly (No doubt about that). Now when you try to resize the event by dragging the EndTime and make the end time = '10/17/2008 2:00 PM' then it will return incorrect value inEndTime Property. It will use the same date as the StartDate and just give the updated time so End Time returns '10/15/2008 2:00 PM' (Note: the date is changed equal to StartDate).
If you tryresize the event to ''10/17/200811:00 AM' then new EndTime propertyreturns , '10/15/2008 11:00 AM' and in that way DayPilot calender does not display this event because the EndTime becomes greater than the start time.
Note: I am using trial version ofthe latest release of DayPilot calendar and this bug is appearing.
Suggestion : when ever an event is longer than 24 hours then display it in the ALLDay Event Row. You can take reference from RAD Schedular control. (dont mind there are also few bugs in RAD Sechdular control)
