I am wondering if anyone know something about this issue. It seems like the default template provided here for ListViewItem does not support DisplayMemberPath of Li
I asked a similar question here
The DisplayMemberPath property is actually a shortcut that will tell WPF to create the default item template with nothing more than a TextBlock with it's Text bound to whatever field is in DisplayMemberPath
If you overwrite the item template in addition to setting DisplayMemberPath, then you are essentially overwriting the template that DisplayMemberPath created for you, so that property becomes useless.
