HierarchicalDataTemplate for very complex layout

Question

Im making a herbal database program and I am having troubles setting up HierarchicalDataTemplates for my main data class.

Tree layout wanted:

Glossary
- Category1
  - Letter (Reduces overall list size)
    - Entry
      - Note1
      - Note2
Herbs
- Botanical Name
  - Alphabetical
    - Letter (Reduces overall list size)
      - Entry
  - By Family
    - Family
      - Entry
- Common Name
  - Letter (Reduces overall list size)
    - Entry

NOTE: All entries have notes NOTE2: Letter is a letter of the alphabet for sorting

Ex:

a
- apple
b
- bus

Main Class:

Public Class MainSystem
    Public herbs As New Dictionary(Of Integer, herbEntry)
    Public glossary As New Dictionary(Of Integer, glossaryEntry)
End Class

GlossaryEntry:

Public Class glossaryEntry
    Public Property ID As Integer
    Public Property Words As List(Of String) 'Each word is in the format: Catagory/word
    Public Property Notes As SortedDictionary(Of String, String)
End Class

HerbEntry:

Public Class herbEntry
    Public ID As Integer
    Public Property commonName As List(Of String)
    Public Property botanicalName As List(Of String)
    Public Property PlantID As PlantID
End Class

EDIT: Thanks to the link from @AngelWPF I have got the tree displaying my object. But, currently the tree looks like this:

Herbs
- Common Name
  - CommonName item from entry
  - Another CommonName item from entry
- Common Name
  - CommonName item from entry
  - Another CommonName item from entry

How can I make this change to match my hierarchy?

XAML:

<UserControl.Resources>
        <HierarchicalDataTemplate  DataType="{x:Type my:herbEntry}">
            <TreeViewItem Header="Common Name"  ItemsSource="{Binding commonName}">

            </TreeViewItem>
        </HierarchicalDataTemplate>
    </UserControl.Resources>
    <Grid>
        <TreeView HorizontalAlignment="Stretch" Name="TreeView1" VerticalAlignment="Stretch">
            <TreeViewItem Header="Herbs" ItemsSource="{Binding herbs.Values}"/>
        </TreeView>
    </Grid>

I still dont have a complete solution, the link @AngelWPF posted helped alot in getting me started, but i still havent found a way to organize the tree. So far, the only method i can think of is to generate custom node objects in the hierarchy that I need and display that. But thats sounds a little too hacky to me. In some ways, WinForms is MUCH easier... — ags131, Oct 08 '11 at 05:52

This example may guide you to assign different item templates at different levels for each type of bound item ...

Thanks! That was very helpful. Now I'm having problems getting the catagories and sorting. Updated post with my partial solution – ags131 Oct 03 '11 at 17:28
