RadCalender error with RadScheduler

[Levi]

I am building a RadScheduler application via a demo that I found online by a member of the Telerik team.  I have everything working but when I try and expand the calendar to 3 Rows (MultiViewRows = 3) and attempt to save it, it throws the following error:

Property accessor 'ZoomLevel' on object 'RadCalendar1' threw the following exception: 'Object reference not set to an instance of an object.'

Thanks for your help!

Before you ask, I should probably give more details.  I have a radCalendar, a radSchedulerNavigator, and a radScheduler.  I have the radCalendar changing the radSchedular when you click on a date with the Navigator on top of the radScheduler.  I have RadScheduler1.ActiveView.StartDate = RadCalendar1.SelectedDate() to handle the event.  I don't really think this has anything to do with it, but y'all are the experts.  This is using Winforms and VS2013 and Visual Studio is the application throwing the error.  If I switch the MultiViewRows back to 1 on the radCalendar, the issue goes away.  Any thoughts?

Hello Levi,

Thank you for writing.

I confirm that this is an issue with our RadCalendar. I have logged it in our Feedback Portal. You can track its progress, subscribe for status changes and add your vote/comment to it on the following link - Feedback Item.

I have also updated your Telerik points.

Currently, due to the specificity of the issue, the possible solution that I can suggest is to set the MultiViewRows property to 1 in combination with HeaderNavigationMode.Zoom or keep the MultiViewRows set to 3, but keep the default HeaderNavigationMode.

I hope this information helps. Should you have further questions, I would be glad to help.

If I set the MultiViewRows to 3, it doesn't see to matter what I do with the NeaderNavigationMode.  On my end, it seems to throw the same error.  I guess I will have to be patient which is fine, but I really like the MultiViewRows functionality especially for the people I am writing this application for.  Thanks for your help.

Hello Levi,

Thank you for writing back.

By default the HeaderNavigationMode property is set to HeaderNavigationMode.Popup. If the MultiViewRows property is set to 3 and the navigation mode is HeaderNavigationMode.Popup, I am unable to reproduce the error. It occurs only when the RadCalendar has HeaderNavigationMode.Zoom and the visible months are more than 1. Please ensure that the HeaderNavigationMode is not modified at design time to Zoom, as a result of which you are obtaining the error. If you are still experiencing any difficulties, could you please specify the exact steps how to reproduce the issue when the HeaderNavigationMode is set to Popup? Thus, we would be able to investigate the precise case and assist you further. Thank you in advance.

I am looking forward to your reply.
