Hi,

       In our application we are using UltraMonthViewSingle and UltraCalendarInfo .

In one of the operations,we are clearing all the appointments of the UltraCalendarInfo.It was working

properly in the initial days.But now we are getting an exception.The message is mentioned below.

"Index 0 is either negative or above rows count"

When we tried find to out the reason behind this,we came to know that this is happening once the number of appointments are  180 or above.

To confirm this,we removed some appointments and tried 

UltraCalendarInfo.Appointments.Clear().This executed without any exception.

Is there any limit for the number of appointments in 'UltraCalendarInfo'?

The code segment which loads the UltraCalendarInfo is given below

ultraCalendarInfo.DataBindingsForAppointments.SetDataBinding(dataset, string.Empty);

The code segment doing clear operation is given below.

if (ultraCalendarInfo.Appointments.Count > 0)
            {
                ultraCalendarInfo.Appointments.Clear();
            }

Is there any solution for this issue?

Thanks,

Jithesh
