I'm trying to use the DataFilter to filter data on my ScheduleView. I have a custom class called StaffResource that inherits from Resource, in which I have several properties such as Staff Name, Office, etc. I only want some of these properties to show up in the Member Dropdown of the DataFilter, so I mark them with Data Annotations. My issue is that I can't get into the base Resource class to mark those 3 properties so they don't show up in the DataFilter. Right now the datafilter shows DisplayName, ResourceName, and ResourceType in the dropdown, which I don't want. How would I get those to not show up?
