示例1: myListView_DragOver
// Moves the insertion mark as the item is dragged.
private void myListView_DragOver(object sender, DragEventArgs e)
{
// Retrieve the client coordinates of the mouse pointer.
Point targetPoint =
myListView.PointToClient(new Point(e.X, e.Y));
// Retrieve the index of the item closest to the mouse pointer.
int targetIndex = myListView.InsertionMark.NearestIndex(targetPoint);
// Confirm that the mouse pointer is not over the dragged item.
if (targetIndex > -1)
{
// 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.
Rectangle itemBounds = myListView.GetItemRect(targetIndex);
if ( targetPoint.X > itemBounds.Left + (itemBounds.Width / 2) )
{
myListView.InsertionMark.AppearsAfterItem = true;
}
else
{
myListView.InsertionMark.AppearsAfterItem = false;
}
}
// 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;
