Scheduler with Web Service & category filtering

[Tim]

I'm trying to implement a scheduler similar to the "First Look" scheduler on the demo site using a WCF service. I've got it working ok, but I can't seem to find all the code for the checkbox filtering. Specifically what happens when in the OnClientsAppointmentsPopulating event is fired. 

What is happening here? 
eventArgs.get_scheeventArgs.get_schedulerInfo().CategoryNames = categoryNames;
It looks like custom data is being sent through ISchedulerInfo, but I can't seem to find any example code showing how this is done.

If someone can point me in the right directions I'd appreciate it.

Thanks.

Hello Tim,

Thank you for your question.
 
I just finished creating a code library entry that will provide you with a stand-alone sample.

You can examine the code and contact us if you have questions.
