As the otehr memers have indicated, it helps to be specific about what the UI is; whether it is ASP.Net, WPF, Windows Forms or whatever. The best way to do that is to put the question in the forum for tha UI; this forum is for questions about the C# language, not all questions about everything and anything developed using C#. This is a UI question, not a language question.
Assuming you are asking about a Windows Forms application, the ListView control is quite old. It was initially developed for the Windows Explorer accessory in Windows 95. It is less flexible than the newer controls.

I suspect kehinde may be talking about the ListView in Windows Forms but, to the best of my knowledge, you can't add controls as (or to) sub-items of that either.
