For example I have a self referencing table such as
Pkparentname
10Inbox
20Deleted Items
31Inbox_subfolder
The problem that I am having is getting the subfolders to display correctly. I am getting a flat view rather than a Hierarchical view.
Any assistance would be much appreciated.
I am using the HierarchicalDataTemplate, although I am not sure if I am using it correctly since I am binding to the same object (Self referencing table).

TreeView and HierarchicalDataTemplate assume the data is already in hierarchical form. Meaning that there's a list of top-level objects, each of which has a property whose value is a list of its children, and so forth. In your case, this might look like:
top-level list: { Inbox, DeletedItems }
Inbox.Children: { Inbox_Subfolder }
DeletedItems.Children: { } (empty list)
You'll need to convert your table to a structure of this form. WPF doesn't have any built-in way to do this for you.
Thank you for your assistance, it happens that I was binding to a folder object in the HierarchicalDataTemplate
rather than the ChildFolders (Collection of childFolders). Code below resolved issue
<HierarchicalDataTemplate ItemsSource="{Binding Path=ChildFolders}">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<TextBlock Margin="4,0,0,0" Text="{Binding Path=Name}" />
</StackPanel>
</Grid>
</HierarchicalDataTemplate>
Thanks
