示例1: Point
' Moves the insertion mark as the item is dragged.
Private Sub myListView_DragOver(sender As Object, e As DragEventArgs)
' Retrieve the client coordinates of the mouse pointer.
Dim targetPoint As Point = myListView.PointToClient(New Point(e.X, e.Y))
' Retrieve the index of the item closest to the mouse pointer.
Dim targetIndex As Integer = _
myListView.InsertionMark.NearestIndex(targetPoint)
' Confirm that the mouse pointer is not over the dragged item.
If targetIndex > -1 Then
' Determine whether the mouse pointer is to the left or
' the right of the midpoint of the closest item and set
' the InsertionMark.AppearsAfterItem property accordingly.
Dim itemBounds As Rectangle = myListView.GetItemRect(targetIndex)
If targetPoint.X > itemBounds.Left + (itemBounds.Width / 2) Then
myListView.InsertionMark.AppearsAfterItem = True
Else
myListView.InsertionMark.AppearsAfterItem = False
End If
End If
' Set the location of the insertion mark. If the mouse is
' over the dragged item, the targetIndex value is -1 and
' the insertion mark disappears.
myListView.InsertionMark.Index = targetIndex
