I'm sure i messed this up somehow, but i can't figure out how at this point.

i had a schedule control with resources on it.  they were colored different colors.  it worked fine.

now i added databinding to add appointments to it.  bound to custom business objects.  now everything shows in a weird gray/black shade. see the example.  if i remove databinding it works fine again (of course there's no appointments).

I can't get the appointment summary to show either.  what am i doing wrong for that?  it's there if i double click and edit an appointment the summary/description are there, so i know binding is correct, but it won't show on the appointment itself.

here's my databinding code.  it's all done in code, nothing on the form itself.

			var appointmentMappingInfo = new AppointmentMappingInfo();
			appointmentMappingInfo.BackgroundId = "ApptStatus";
			appointmentMappingInfo.Description = "Description";
			appointmentMappingInfo.End = "EndDate";
			//appointmentMappingInfo.Location = "Location";
			//appointmentMappingInfo.MasterEventId = "ParentID";
			//appointmentMappingInfo.RecurrenceRule = "RecurrenceRule";
			appointmentMappingInfo.ResourceId = "ProviderId";
			//appointmentMappingInfo.Resources = "SchedulerAppointment";
			appointmentMappingInfo.Start = "StartDate";
			//appointmentMappingInfo.StatusId = "StatusID";
			appointmentMappingInfo.Summary = "Subject";
			schedulerBindingDataSource1.EventProvider.Mapping = appointmentMappingInfo;
 
 
			var resourceMappingInfo = new ResourceMappingInfo();
			resourceMappingInfo.Id = "Id";
			resourceMappingInfo.Name = "Name";
 
			schedulerBindingDataSource1.ResourceProvider.Mapping = resourceMappingInfo;
 
			_bsAppts = SchedulerRepository.GetAppointments();
 
			schedulerBindingDataSource1.ResourceProvider.DataSource = _opList;
			schedulerBindingDataSource1.EventProvider.DataSource = _bsAppts;
 
 
			schMain.DataSource = schedulerBindingDataSource1;

_opList is a binding list of your Resource object.
_bsAppts is a binding list of my business object appointments

Thanks!

EDIT to get the appintment summary to show, i had to handle the appointmentformatting event and change the forecolor of appointmentelement to black.  i still have the weird color problem above.

Hi John,

Despite my efforts, I was not able to replicate the case on my end using the reported scenario and code snippets. Please try to isolate the issue in a sample application including bound and unbound appointment processing with AppointmentFormatting event handler and send it to us with some part of your data to investigate it locally. This will allow me to provide you with adequate and helpful assistance.

Thank you for your time and cooperation. I am looking forward to your reply.

i was able to reproduce it by just binding to a custom object.  
i can't attach a project to this but here's what i did.  I'm using 2013 q1

drop a scheduler on a form and call it schMain.

replace your form1 code with the code below.  it will reproduce the issue.
in the load event of the form, there's a method called BindForm.  if you comment out this line, it works.  the resources are all in color like they should be.  if you put the line back in, it breaks and they all go gray.  i attached screen shots of what i see too.

thanks!

while playing with the reproduction project, i actually fixed the problem.  it shouldn't matter what order it's done in, so i think it's a bug but the work around is to bind the form before adding the resources.  it seems to work with limited testing so far.  My new load code is as follows:
note the bindform call is now above addresources.  that produces the attached screen shot which is what i wanted.

var dayView = schMain.GetDayView();
 
            dayView.DayCount = 1;
 
            dayView.RulerScaleSize = 15;
 
            _opList = new List<Resource>();
 
            BindForm();
 
            AddResources();
 
            foreach (var itm in _opList)
            {
                schMain.Resources.Add(itm);
            }
 
            schMain.GroupType = GroupType.Resource;
            dayView.ShowHeader = false;
            dayView.ShowAllDayArea = false;
            schMain.ActiveView.ResourcesPerView = 4;
