Appointment Persistence

[Mark]

Hello,

I have created an application using the ScheduleView control and would like to persist the appointments.  If I try to use typical serialization methods, I get an exception saying that AppointmentBase is not serializable.  Does anyone know what the best approach is to save appointments to a file?

Thanks,
Mark

Hi Mark,

You could try serializing the appointments in iCal format:

Hi Valeri,

Thanks for the reply.  I meant to post my workaround earlier, but that is exactly what I ended up doing.  I export the appointments to a string and persist the string.  Then when I load my file I import the appointments from the string.  So far it seems to be working pretty well.  If there is a better approach then I am all ears!

Thanks,
Mark

Actually, one thing that is frustrating is that not all properties get persisted in this way.  For example - the categorization colours do not get persisted or restored.

I am curious as to what this control was expected to be used for when you cannot persist appointments easily.  I feel like I am missing some critical piece of information that will make it all make sense!  Am I?

Hello Mark,

This seems like a bug on our side and I am surprised that no one reported it for RadScheduler, as the code that persists the appointment properties is the same in both controls. We will fix this problem with the upcoming service pack this week.

Your points have been updated.

We are using the 2010.3 1314 version of the RadScheduleView and the categories are exported in the iCal string but never restored when the iCal string is imported. We also tested the Q1 2011 beta and the problem still occurs. We rely on the categories in our solution so is there a plan to fix this bug in the short term?

Thanks for the feedback

Hi Francis,

It seems that the bug is still present in RadScheduleView. We will provide a fix with the internal build next Monday (it will be included in the Q1 2011 release as well).

Your points have been updated.

All the best,

Hi is this still an issue, I am using the the Q1 2011 wpf controls(trial RadControls_for_WPF_35_2011_1_0419_Trial) and cannot serialise Appointmentbase and receive the following error:

Hello Rob,

Yes, AppointmentBase is not serializable, the suggested approach is to serialize the appointments in ICal format as explained earlier in this thread.
