Drag over Listview ande Cuse Event over each item

I would love to be able to drag and Drop from a Treeview to a MSFlexGrid but I understand it is not possible. If it is please let me know how. So i am trying something different.

What I want to do is have two listview boxes. The first box has say 3 items 1,2,3. The user clicks on number three and holds down the mouse and drags it over a second listview that has 3 names george, fred ,and steve. I want to fire an event every time the user passes the mouse over a user name. Remember, they are still holding down the mouse to drop.

Can this be done and if so any ideas on which event I should use.

Thanks
