I am trying to prevent the user from resizing an appointment such that it would overlap with another appointment within the same resource. The problem seems to be when the end of the appointment being resized is dragged over another that is only 1 day in duration, it's not detecting that appointment as being within the start and end dates. I'm using the timeline view where each slot is 1 day.
I can set the start time that it passes to the function to one ms less where it spans the day boundary and it works. If I set it back to 00:00:00 it doesn't.
The code I'm using is below, ResizingTarget() is the handler for the scheduler's OnClientAppointmentResizeEnd event.
function
ResizingTarget(sender, args)
{
if
(!isSlotFree(args.get_targetSlot(), args.get_appointment()))
{
args.get_appointment().get_element().style.border =
"0px none black"
;
args.set_cancel(
true
);
}
else
{
var
apt = args.get_appointment();
var
newTime = args.get_newStartTime();
var
featureId = apt.get_id();
// Call web service to update target
}
}
function
isSlotFree(targetSlot, appointment)
{
//Get start time of target calendar slot
var
startTime = targetSlot.get_startTime();
//Ensure reference to RadScheduler client object
if
(_sched ==
null
)
_sched = $find(
"<%= targets.ClientID %>"
);
//Calculate end time (to create span that cannot be overlapped)
var
endTime =
new
Date(startTime.getTime() + 86400000);
//24hr period
startTime =
new
Date(startTime.getTime());
//Determine if appt being moved overlaps with another appointment
return
!overlapsWithAnotherAppointment(appointment, startTime, endTime);
}
function
overlapsWithAnotherAppointment(appointment, startTime, endTime)
{
if
(_sched ==
null
)
_sched = $find(
"<%= targets.ClientID %>"
);
// Get all appts in range of start and end time
var
appointments = _sched.get_appointments().getAppointmentsInRange(startTime, endTime);
if
(appointments.get_count() == 0)
return
false
;
var
strID =
""
;
var
apptCnt = appointments.get_count();
for
(
var
i = 0; i < apptCnt; i++)
{
if
(appointments._array[i]._id != appointment._id)
{
if
(appointments._array[i]._serializedResources[0].key == appointment._resources._array[0]._key)
return
true
;
}
}
return
false
;
}
