I am using the XamTreeGrid and here is the xaml:

<igDP:XamTreeGrid DataSource="{Binding ChangesList, RelativeSource={RelativeSource FindAncestor, AncestorType=UserControl}}" Grid.Row="1" BorderThickness="1" BorderBrush="Silver">
                                    <igDP:XamTreeGrid.FieldSettings>
                                        <igDP:FieldSettings AllowRecordFiltering="True" DataItemUpdateTrigger="OnCellValueChange"/>
                                    </igDP:XamTreeGrid.FieldSettings>
                                    <igDP:XamTreeGrid.FieldLayoutSettings>
                                        <igDP:FieldLayoutSettings AutoGenerateFields="False" />
                                    </igDP:XamTreeGrid.FieldLayoutSettings>
                                    <igDP:XamTreeGrid.FieldLayouts>
                                        <igDP:FieldLayout Key="SyncItems">
                                            <igDP:CheckBoxField Label="" AlternateBinding="{Binding IsSelected, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" Width="Auto"/>
                                            <igDP:Field Name="Description" AllowEdit="False" Width="350"/>
                                            <igDP:Field Name="User" AllowEdit="False" Width="Auto"/>
                                            <igDP:Field Name="DateTime" AllowEdit="False" Width="Auto"/>
                                            <igDP:Field Name="SyncItems" />
                                        </igDP:FieldLayout>
                                        <igDP:FieldLayout Key="ChildSyncItem">
                                            <igDP:Field Name="Description" AllowEdit="False"/>
                                            <igDP:Field Name="User" AllowEdit="False"/>
                                            <igDP:Field Name="DateTime" AllowEdit="False"/>
                                            <igDP:Field Name="ChildSyncItems" AllowEdit="False" IsExpandable="True"/>
                                        </igDP:FieldLayout>
                                    </igDP:XamTreeGrid.FieldLayouts>
                                </igDP:XamTreeGrid>

Hello Lin,

Thank you for your post.

It has been a while since you have made your post, in case you still need support I will be glad to assist you further. I have been looking into it, but it seems like I am missing something from your scenario, so if this is still an issue for you, could you please send me, an isolated sample project, where this is reproduced, so I can investigate it further for you.

Also would you please take a look at this forum thread and try similar approach with XamTreeGrid:

Looking forward to hearing from you.

if you have interface structure like this, it will show as PO describes:
public interface IManager : IPerson, IRole

Manager : IManager

and IPerson defines Name, Age; IRole defines Title and other stuff.

Fields are trying to display Name, Age, Title, and when the binding source is empty, the grid will show as empty without column header.
