I drag a RadScheduler to my webform, and start debug, then I get an error message as following. Please tell me how to solve the problem. Thank you very much for your helping.

Error says it all. These fields need values to be able to display the Scheduler. Have you assigned any values for them?

[Vinix]

I already solve the problem.
Thank you very much.

is there a way to turn off databinding and just fill appointments manually? or do i have to implement custom dataprovider. The exchangeprovider in the sdk doesn't work or i'd use that

[Boyan Dimitrov]

Hello,

The RadScheduler object provide an InsertAppointment method that expects an appointment object. This way you can manually add an appointment instead of setting data source.

yes I got that thanks - there's no problem inserting appointments however even if you're not using databinding you apparently have to fill out values for DataKeyField etc - this is either a bug or very irritating 'feature'

[Boyan Dimitrov]

Hello,

Indeed you have to set the required fields such as DataKeyField , DataSubject and etc in order to run the RadScheduler control, unless you use a custom provider.
