Reorder a winforms listbox using drag and drop?

Question

Is this a simple process?

I\'m only writing a quick hacky UI for an internal tool.

I don\'t want to spend an age on it.

7 Years Late. But for anybody new, here is the code.

private void listBox1_MouseDown(object sender, MouseEventArgs e)
    {
        if (this.listBox1.SelectedItem == null) return;
        this.listBox1.DoDragDrop(this.listBox1.SelectedItem, DragDropEffects.Move);
    }

    private void listBox1_DragOver(object sender, DragEventArgs e)
    {
        e.Effect = DragDropEffects.Move;
    }

    private void listBox1_DragDrop(object sender, DragEventArgs e)
    {
        Point point = listBox1.PointToClient(new Point(e.X, e.Y));
        int index = this.listBox1.IndexFromPoint(point);
        if (index < 0) index = this.listBox1.Items.Count - 1;
        object data = listBox1.SelectedItem;
        this.listBox1.Items.Remove(data);
        this.listBox1.Items.Insert(index, data);
    }

    private void itemcreator_Load(object sender, EventArgs e)
    {
        this.listBox1.AllowDrop = true;
    }
