[Solved] ResourceTypeCollection Resources

[Alexis]

Hello,

I'm using RadScheduleView control and can not get to add / remove Resources for grouping through code-behind. However if I add it in the XAML, if you let me. The fact is that I need to add / remove Resources as the number of items that receipt of a WCF. This is snippet of how I add / remove Resources: 

var rtc = radScheduleView.ResourceTypesSource as ResourceTypeCollection;

var rt = rtc[0];

var appoints = ((InspectoresCalendarViewModel) DataContext).Appointments;

foreach (var appoint in appoints)
{
    rt.Resources.Add(new Resource(appoint.Inspector));
}

rtc.Remove(rt);
rtc.Add(rt);

radScheduleView.ResourceTypesSource = rtc;

Need help.
Thank you.
