Hello, 

I'd like to put a XamTreeGrid in XamTabContol. 

I wrote this code, and the Name and subNode's rows are shown with branch lines.

However, I cannot see the subNode's strings.

How can I fix it? 

<ig:XamTabControl>
    <ig:TabItemEx>
        <ig:XamTreeGrid DataSource={Binding TreeItemList}>
            <ig:XamTreeGrid.FieldLayouts>
                <ig:FieldLayout Key="TreeItemClass">
                    <ig:TextField Name="Name" />
                    <ig:Field Name="SubnodeItemList"/>
                </ig:FieldLayout>
            </ig:XamTreeGrid.FieldLayouts>
        </ig:XamTreeGrid>
    <ig:TabItemEx>
<ig:XamTabControl>

public class TreeItem Class
{
    public string Name { get; set; }
    public ObservableCollection<string> SubnodeItemList { get; set; }
    
    public TreeItemClass()
    {
        SubnodeItemList = new ObservableCollection<string>();
    }
}

public class ViewModel
{
    public ObservableCollection<TreeItemClass> TreeItemList { get; set; }
    
    public ViewModel()
    {
        TreeItemList = DataList;
    }
}
