RadScheduler OnClientAppointmentDoubleClick get_appointment() returns null

Please advise what is wrong with the below code since get_appointment returns null when going thru OnClientAppointmentDoubleClick(sender, eventArgs)
ASP.NET version: 4.0
OS: XP
browser version: Google Chrome 27.0.1453.110 m
Telerik product v. 2010.3.1215.40

Thanks!
Antonio

Hello,

 
I have tested the issue you described with the version of RadControls that you shared(2010.3.1215.40) but could not observe any unusual behavior.  I am attaching my sample web page with RadScheduler that is bound to dummy XML database. Please review it and let me know if you have further question or your scenario is somehow different.

Hi Plamen,

Thank you very much for you code, it was really helpful on order to solve my issue. in your example you don't use prerender which was the issue at my code. I've learned that both onprender and OnClientAppointmentDoubleClick can not be used at the same time, arguments will be null. I just removed onprerender and problem is gone!

Thanks again

Antonio
