hierarchicaldatatemplate

I have a set of data that is structured like this:

 ItemA.GroupA
 ItemB.GroupA
 ItemC.GroupB
 ItemD.GroupC

I need to present the data in a WPF Tree View like this:

GroupA

--- ItemA

--- ItemB

GroupB

--- ItemC

GroupC

--- ItemD

What XAML can I use to group the leaves by distinct value? For instance, there could be multple items in the collection which are GroupA.ItemA, however, I only want to present the node and leaf once.

One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
