Hi Jackieliu,

let's say you want to show only 2 levels, you need to define 2 FieldLayouts.

<FieldLayout Key="Network">

<Field Name="NetworkProperty1"/>

<Field Name="NetworkProperty2"/>

<Field Name="Domains"/> *name of the property that returns you IEnumerable that contains next level of data.*

</FieldLayout>

<FieldLayout Key="Domain">

<Field Name="DomainProperty1"/>

<Field Name="DomainProperty2"/>

</FieldLayout>

</FieldLayout>

Joe,

I have a hierarchical structure like below. When I bind an instance of NetWork to the XamDG, all these 4 levels will be displayed by default with AutoGenerateFields="True". What if I want to show only 2 or 3 level? I set AutoGenerateFields="false" and defined 2 FieldLayouts, it didn't work as intended. Only top level was shown. Do you have any idea on that?

Thanks,

Jackie

public class NetWork
    {
        public ObservableCollection<Domain> Domains { get; set; }
    }
    public class Domain
    {
        public ObservableCollection<Machine> Machines { get; set; }
    }
    public class Machine
    {
        public ObservableCollection<Service> Services { get; set; }
    }
    public class Service
    {
        public ObservableCollection<Child> Children { get; set; }
    }
    public class Child
    {
    }

Hi,Joe, thanks for your reply, it can work if the datasource is dataset, but how about the datasource is ObjectDataProvider? I tried this type datasource, it seems defining both parent field layout and child field layout can't work.
