How to extend a Windows Forms Control

[Al Reid]

I need to extend a couple of controls to add a few custom properties, methods, etc. What is the correct way to do this. My first
attempt (inheriting the control and adding the properties and methods) seems to work. However, several times the IDE has lost the
controls. BTW, I'm using VB2005.

Mhm... This should basically work. Alternatively you could write an
extender control.

It works great until the controls get lost. The form Designer looses the controls, but keeps the Declaration (Withevents ..). One
of the extended controls is a listView. When it gets lost, the ColumnHeaders don't get lost, but the Listview does. Very Strange!
