Max,
It depends on the amount of data you want to display.

We use a treeview to display project/plans/tasks in our application. We break up the initial load so that only projects are loaded. Once a project is selected/expanded the plans for that project are loaded. When the plan is expanded, the tasks are loaded. When a user has access to less than 200 projects, the initial load time is not noticable. However, if a user has to load 1000s of projects, there is a noticable performance hit on both the initial load and the subsequent unload when the form is destroyed.

I don't currently use the ListView so I can't comment on that.
