Add Group Collapse Behavior on a Listview Control

Introduction

ListView control is an important but complex control in the WinForm environment. Group behavior is added into this control, but unfortunately, we can't collapse or expand the group.

I'll show how to use some simple code to add collapse/expand behavior on the ListView control.

This is a sample image on Windows Vista and Windows Server 2008:
