RADScheduleView: Index was out of range

[Gianluca Ciocci]

Hi,
I have this error when I set the Appointmet collection:
"Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index"

the Stack trace is:

Hello Gianluca,

Most probably in the appointments collection there is an appointment with specific properties that trigger a bug in RadScheduleView. Is it possible for you to send me a simple application that could be used to debug the problem? Just open a support ticket and attach the project there.

Kind regards,

Hello Valeri,

I found the cause of my problem...
In my xml datasource there are many items with the Start Date > End Date (it is an error!) and this condition throw an exeption on Appointment RADScheduleView DataSource.

That's all.

King Regards,
