  Hello,
  
  I have seem some posts similar to what I'm trying to do (but now the same thing):
  
  I have treeview bound to a list of business objects of type PieceGroup, that represents a group of pieces that must be produced. The items on the treeview are groupd by the Material property (complex type). This is working fine.
  
  Now, I would like to have child nodes of every material type that are not members of the material property, so I will have to build the list of children programatically. I was thiniing about using a converter, but it seems not to be working. Here is what I'm doing today
  
  

  <pre lang=x-xml><CollectionViewSource x:Key="MaterialProcessingSource">
              <CollectionViewSource.GroupDescriptions>
                  <PropertyGroupDescription PropertyName="Material">
                  </PropertyGroupDescription>
              </CollectionViewSource.GroupDescriptions>
          </CollectionViewSource>
  
          <DataTemplate x:Key="repositoryTemplate">
              <StackPanel Orientation="Horizontal">
                  <TextBlock Text="{Binding Path=width"/>
                  <TextBlock Text=" X "/>
                  <TextBlock Text="{Binding Path=length}"/>
              </StackPanel>
          </DataTemplate>
  
          <HierarchicalDataTemplate x:Key="detailDataTemplate"
              ItemsSource="{Binding Path=Items}" ItemTemplate="{StaticResource repositoryTemplate}">
              <StackPanel Orientation="Horizontal">
                  <TextBlock Text="{Binding Items[0].Material.code }"/>
                  <TextBlock Text=" - "/>
                  <TextBlock Text="{Binding Items[0].Material.description }"/>
              </StackPanel>
          </HierarchicalDataTemplate>
  

  
  
  I think that I must somehow change my detailDataTemplate binding to bind to a runtime generated list, based on my business requirements. How can I do that?
  
  Thanks in Advance,
  
  Igor
