Hello, I have a XamDataTree defined as follows:

<ig:XamDataTree x:Name="_MenuTree"
                        ItemsSource="{Binding Menus}"
                       SelectedDataItems="{Binding SelectedMenuItems}"
                        NodeLineVisibility="Visible"
                         IsExpandedMemberPath="IsExpanded"
                        NodeCheckedChanged="TreeNodeCheckedChanged">
                    <ig:XamDataTree.CheckBoxSettings>
                              <ig:CheckBoxSettings CheckBoxVisibility="Visible"
                                                           CheckBoxMode="Auto" />
                    </ig:XamDataTree.CheckBoxSettings>
                    <ig:XamDataTree.SelectionSettings>
                                          <ig:TreeSelectionSettings NodeSelection="Multiple" />
                     </ig:XamDataTree.SelectionSettings>
                     <ig:XamDataTree.GlobalNodeLayouts>
                                              <ig:NodeLayout Key="MenuLayout"
                                                                       TargetTypeName="clsMenuItem"
                                                                       DisplayMemberPath="Description"
                                                                       CheckBoxMemberPath="IsSelected">

                                               </ig:NodeLayout>
                        </ig:XamDataTree.GlobalNodeLayouts>
</ig:XamDataTree>

The Menus property is in the ViewModel and is an ObservableCollection of clsMenuItem. clsMenuItem has the following properties: ID (int), Description (string) and ChildItems (ObservableCollection(of clsMenuItem))

I looked at one of the other similar posts on the forums board, but in my case, I don't see anything on the screen when then form loads, even though the Menus property has proper stuff in it.

What am I missing / doing wrong?
