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.

The listview works fine. It's performance depends on the amount of data going into it.

I've never really understood why the listview and treeview are so much faster in VB than VFP. No comparison.
