Thanks, but this does not really help. i need to use the SharePoint Client Object Model, run a caml query to grab items from a SharePoint Calendar List, and render those in your ScheduleView control. I have done it with the RadScheduler when my main page loads. Basically following the approach done in the video by Sahil Malik. However, I cannot seem to get it to work given the changes around AppointmentsSource, using the ViewModels etc without a ton of code. Maybe I am missing something, but I need to abandon this control and it's use with SharePoint and go back to the RadScheduler.
