Embedded GroupBox in ListView

Question

I have a custom class NewsBox derived from GroupBox, with a couple of standard labels in each NewsBox.

I'm looking to put these into a ListView, so basically rather than a list of text in columns, a list of groupboxes.

listView1.Controls.Add(new NewsBox());

The above works for the first box, but doesn't show any ones after that.

How would I go about accomplishing what I need?
