Yes, that's correct. I guess one of the things I had been thinking about when I replied, was some of the dynamic instantiation I used to do at a past company, using Reflection to load and display various UserControls in a Panel ... kind of an Outlook-style of design using SideBars on the left side and the Panel with the UserControl on the right. We never kept any references to the UserControl once we switched to another, but that design was way different than what Pete was talking about with TabPages.
