VS 2010 Listview Items

Hello.

Ive got a listview with 3 columns- Date / Time, User and Details. When a user clicks on an item, highligting it and then presses a button, a form then shows up with 3 textboxes with the same names as the columns. How do i get it so the details on the item selected is placed in the corresponding boxes?

Does this make sense?

Thanks
