Wpf Treeview bind base on Project Folder Structure

Question

I currently have a catalog of files I want to read into my program in my Project. Structure.

Project
   - Properties
   - References
   - Manufacturers (want to project this as treeview)
      - Honda
         - file1
         - file2
      - Toyota
         - file1
         - file2

In my program each file above is represented by its own business object. I want to be able to in my program have this in my treeview.

- Honda
     - file1
     - file2
- Toyota
     - file1
     - file2

I only load these file once so I want to just read these file once and bind them to the tree view. Is there an elegant way to do this???

Thanks, Kev

You can make use of a HierarchicalDataTemplate

<toolkit:HierarchicalDataTemplate x:Key="FileTemplate" >
       <TextBlock Text="{Binding Path=FileName}" />
</toolkit:HierarchicalDataTemplate>
<toolkit:HierarchicalDataTemplate x:Key="ManufacturerTemplate" 
        ItemsSource="{Binding Path=Files}" 
        ItemTemplate="{StaticResource FileTemplate}">
        <TextBlock Text="{Binding Path=Name}"/>
</toolkit:HierarchicalDataTemplate>

<toolkit:TreeView ItemsSource="{Binding}" 
    ItemTemplate="{StaticResource ManufacturerTemplate}"/>

Your business objects could look something like this...

class Manufacturer
{
     String Name {get; set;}
     ObservableCollection<File> Files {get; set;}

}

class File
{
     String FileName {get; set;}
}

You would then set the DataContext of the TreeView to ObservableCollection<Manufacturer>
