Not sure if I am in the correct forum for this post but here goes...
I am wanting to create a property against a "Service" object lets say - "LastService" and would like this property value to be generated by a query.
Such that the "LastService" is in itself a "Service" object but is the previous Service for the given Services Customer.
The end result I was hoping for is a datagrid of services, each of which has a cell for Last Service and would be the customers last service before the given one in the list.
Not really sure where to start, can I create a custom property like this? After all the related Customer to Service for example is a related entity which is queried from the server (when lazy loaded)
Thanks in advance
