C# Listview Drag and Drop Rows

Ensure that AllowDragDrop is set to true.

Implement handlers for at least these 3 events

private void myList_ItemDrag(object sender, ItemDragEventArgs e)
    {
        DoDragDrop(e.Item, DragDropEffects.Link);
    }

    private void myList_DragEnter(object sender, DragEventArgs e)
    {
        e.Effect = DragDropEffects.Link;
    }

    private void myList_DragDrop(object sender, DragEventArgs e)
    {
        // do whatever you need to reorder the list.
    }

Getting the index of the row you dropped onto may look something like:

Point cp = myList.PointToClient(new Point(e.X, e.Y));
ListViewItem dragToItem = myList.GetItemAt(cp.X, cp.Y);
int dropIndex = dragToItem.Index;
