I think the part you're missing is the fact that the sender parameter to the event handler method will always be whichever control it is that is raising the event. Before using it though, I would cast it to the correct type so you get the full advantages of intellisense and compiler type checking.
Private Sub Panel1_MouseHover(ByVal sender As Object, ByVal e As System.EventArgs)
Dim panel As Panel = CType(sender, Panel)
panel.BackColor = Color.White
End Sub
