I found the following article for mapping my datasource to the scheduler control.
I'm having the following problem.
I mapped every single property for the appointment collection [See code below] also In my model view I added collections for ResourceItems and Calendars and i instantiate them in my init method in my model view [See code below]. I added for my event items an OwningResourceId and an OwiningCalendarId that return the intance ids from my initialized method.
WWhen I run I keep getting the following error:
'Collection property 'Infragistics.Controls.Schedules.ListScheduleDataConnector'.'AppointmentPropertyMappings' is null.'
When I add an appointments class and a collection in my model view and dump my event values directly then everything works...my problem is that I have properties in my custom business object that i want to utilize to customize the scheduler data presenter template....I tried to add the fields i needed into the Appointment class and dump my needed field values so that I could use them when customizing the template but they don't seem to be picked up at all... how do i handle this problem?
var Apps2 = EventCollection.Select(r => new Appointment { Id = r.EventId.ToString(), Start = r.EventStartDate.GetValueOrDefault(Convert.ToDateTime(r.EventDate)), End = r.EventEndDate.GetValueOrDefault(Convert.ToDateTime(r.EventDate)), OwningCalendarId = "cal0", OwningResourceId = "res0", Subject = r.EventName, Description = r.EventNotes, IsTimeZoneNeutral = true, FightCount = r.FightCount, HasTitleFight = r.HasTitleFight }); foreach (var App in Apps2) Appointments.Add(App);

Hello,
I apologize for the confusion but we had an issue in the documentation that was fixed in version 2011.2. You have to explicitly define the AppointmentPropertyMappingCollection and then put the AppointmentPropertyMapping(s) in it. Here is the link to the same topic in the 2011.2 documentation:
http://help.infragistics.com/Help/NetAdvantage/WPF/2011.2/CLR4.0/html/xamSchedule_Using_Connector_Mapping.html
Let me know if you need any further assistance.
Thanks,

Sorry but this did not help me at all that's the same link i referenced in my question post.
What I'm trying to do to get around the fact that i cannot have my own custom variables to bind to and change the gui is the following.
I created the extra properties in the appointment class as described in my earlier post. I then proceeded to change the template for xamscheduler control to display a green box on my appointment entries in the calendar.
I succeeded adding the rectangle the only problem is that I don't want to display the green rectangle legend on all appointments only on some...that's why I need my custom properties.
so I changed my code to do the following
<Rectangle Name="TitleRec" Tag="{Binding Id}" Width="10" Height="10" ToolTip="This event has a title fight." Stroke="White" Fill="Green" Visibility="{Binding Path=DataContext.Appointments[1].HasTitleFight,RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Window}},Converter={StaticResource boolToVisibility}}" HorizontalAlignment="Right"></Rectangle>
My problem is that I'm not sure how I can get the Id [From the Appointment.Id] to pass it in my bindings Binding Path=DataContext.Appointments[Id].HasTitleFight
Can this even be done? Help please!
I found the problem. On our tables the appointment enddate is optional because we always default to startdate if endate is null. I created a custom variable to do this for me and binding to this instead and it worked. I wasn't getting any error messages regarding this, it was just not painting the appointments.
Hi,
There's no limit on number of items. Is anything different about the data structure - maybe column names?

Is there such a thing as a Max collection size when doing custom mapping? I'm testing my changes in one server that has very few entries and all of my appointments showed.
When I switched to another server that is retrieving almost 4,000 entries no appointments get render...but if instead of trying to map my object collection I dump it into the built in Infragistics Appointment class object and create an appointment collection [dumping the same properties i had mapped through xaml for my custom collection] all of the appointments show.
Diyan was addressing your specific question about the exception. His response was correct. Basically since the mappings properties are get/set (in order to support binding) you have to set the property to an instance of the appropriate collection. I.e. you don't have the <ig:AppointmentPropertyMappingCollection> tags surrounding your <ig:AppointmentPropertyMapping> instances.
<ig:ListScheduleDataConnector.AppointmentPropertyMappings> <ig:AppointmentPropertyMappingCollection> <ig:AppointmentPropertyMapping /> </ig:AppointmentPropertyMappingCollection> </ig:ListScheduleDataConnector.AppointmentPropertyMappings></ig:ListScheduleDataConnector>
If the Rectangle in this reply is within the AppointmentPresenter and you wanted to access a property on the dataitem that the AppointmentPresenter represents then you could probably just bind with a path of Activity.DataItem.HasTitleFlight (without the relative source).
