I'm wanting to use a listview control as a custom menu. Created a usercontrol, added a listview and populated it with groups and items in each group. I then added it to a ToolStripControlHost, and this was in turn added to a ContextMenuStrip which serves as the dropdown for a menu item on my form. Works fine except that the groups don't show up. The listview items are there but no groups. What might cause this? This image:
shows the usercontrol in the designer and also at runtime. Thanks in advance.
