Hi rajesh,

1) This is a known bug in the RadScheduler which have been fixed in version 2011.3 1215:

Fixed: Appointments will get a custom attribute named "Reminder" when setting the reminder through a template. This can cause an exception with declarative data sources

2) You need to make sure that you have setters in the Bindable properties in code-behind of the Advanced Form as shown in this demo:

[Bindable(BindableSupport.Yes, BindingDirection.TwoWay)]
        public object RoomID
        {
            get
            {
                return ResRoom.Value;
            }
  
            set
            {
                ResRoom.Value = value;
            }
        }

If this doesn't helps could you please show me the code so I can inspect it and help you?

hi Veronica,
Thanks For Reply ,i solved the second issue...but isn't there any  solution for the reminder issue for  ASP AJAX Version 2010 Q2... controls also i cant avoid using entity data source because our site is based on Using Dynamic Data website  ...radscheduler has been perfectly working for all my requirements except that reminder issue...i fear it will become a mess if i dont solve that problem and entire work done for the Radscheduler will be wasted...i hope u will reply with a solution for that issue ...as soon as possible 

thanking you 
Rajesh.

Hi rajesh,

Unfortunately we can not provide a workaround for the issue. Upgrading to higher version is the only solution. 

Please accept my apologies for the caused inconvenience.

Kind regards,
