Data Binding & WPF

Question

I've come across an interesting situation whilst starting to work with the WPF framework.

I have the following code to create an ObservableCollection of type Foo

ObservableCollection<Foo> myFoo;

Foo has the following Properties:

• String Name
• String Folder
• ObservableCollection Items

Both Name and Folder have the OnPropertyChanged event implemented (Items already uses ObservableCollection so I believe no additional implementation work is necessary).

For every item within myFoo I would like to show the following:

• Name
• Folder
• Every value of FileInfo.FullName within Items.

e.g.

• Test Name 1
• Test Folder 1
• FileA.JPG
• FileB.JPG

• FileC.PNG

• Test Name 2

• Test Folder 2
• FileD.JPG
• FileE.JPG
• FileF.JPG

I've implemented the binding for the Name and Folder properties, however I'm not too sure on how I should implement binding the value of each Items.FileInfo.FullName occurance.

Would I need to implement a Converter?

Many thanks for your help.

You need to look into HierarchicalDataTemplate. Maybe start with this question.
