ViewModel should contain flat/primitive types OR complex Dto objects

Last Modified: 2013-11-08
Hello there,

I am using ASP.NET MVC 1.
I have DataTransferObjects like (CustomerDto, OrderDetailDto etc). Each of my View has its own ViewModel class. My question is "What is the BEST practice to create ViewModel".

Should I only include primtive/flat types in ViewModel as follows:

In this case, I almost need all the elements defined in CustomerDto and OrderDetailsDto.

public class ViewDataForDetailsView
    public string customerName;
    public string customerAddress;
    public string orderNumber;
    public string orderDate;

can I use existing Dtos as follows:
public class ViewDataForDetailsView
    public CustomerDto customerDetails;
    public OrderDetailsDto orderDetails;

What are the pros and cons of each of the above metioned methods?

Thanks in advance!
