Underlying Dataitems in the ResourceType

[Dan]

I am looking for a way to access other dataitems in in code-behind other than the KeyField, TextField and ForeignKeyField in the Resource object. 

<telerik:ResourceType KeyField="ID" Name="Room" TextField="RoomName" ForeignKeyField="RoomID"  DataSourceID="RoomsDataSource">

My datasoure is based off of a class with multiple properties and when scheduling a new appointment my custom attributes from the scheduler are empty.  

Thanks in advance.
