hello

here is my xaml 

<ig:XamOrgChart ItemsSource="{Binding SelectProClass}" DisplayMemberPath="Name">
       <ig:XamOrgChart.GlobalNodeLayouts>
              <ig:OrgChartNodeLayout Key="ProtocolClasses" TargetTypeName="ProtocolModel" DisplayMemberPath="Name">
                       <ig:OrgChartNodeLayout.ItemTemplate>
                             <DataTemplate>
                                    <TextBlock Text="{Binding Data.Name}"/>
                              </DataTemplate>
                        </ig:OrgChartNodeLayout.ItemTemplate>
             </ig:OrgChartNodeLayout>
     </ig:XamOrgChart.GlobalNodeLayouts>
</ig:XamOrgChart>

Binding Class is ObservableCollection<ProtocolClass> SelectProClass

but I can't see anything

Maybe it's because I'm not using datacontext.

However, because my viewmodel uses prism mvvm , it cannot be used as a data context.

Is there any way to do binding without using this?
