How to assign a list of dynamic values to a report parameter

Example Comments

Im having an issue with this approach.

I have in my report a BindingSource that is setted as the DataSource for the report, and i have a custom method that provides data to the DataSource of the report, so i dont need any DataAdapter (it is set to null)

When i try to set the DynamicListLookupSetting (using the EUD as if i was and end-user, running the application), i need to set up the DataMember, but it happens that i dont want any data member, i want the parameter to be in the same context as my datasource and not inside one member. With this, i cannot provide the ValueMember and DisplayMember correctly.

Here is a example, suppose i have as the source of my report a List<SomeClass>

here is SomeClass

        public class SomeClass
        {
            public string Id { get; set; }
            public string Name { get; set; }

            public List<Orders> Orders { get; set; }
        }

And inside my report i show all the "Orders" of one SomeClass only, and i want to filter by this class and show to the user the parameters with the List of available SomeClass instance.

Since my report source is already the List<SomeClass> o should be able to just set the DynamicListLookupSetting DataSource to my DataSource, and select the Value and Display members, but it is not possible, how could i override or correct this behavior?

Thanks
