[2005] How to draw windows control on top of existing control?

I'm creating a custom user control that inherits from a third party control. For simplicity, let's just say I'm inheriting from a ListView. Depending on some criteria, I need to "draw" on top of a particular location in the ListView at runtime another control, like say a TextBox. Is this possible and if so, a quick example of how do accomplish this would be appreciated.

If it's actually not a ListView then the details will differ, but the principles should be the same.
