I wish this help you I want to drag and drop that I have drawn on the forms. Here is my code for drawing the rectangle. An this works fine. , I have written a helper class for this kind of stuff:

code :

class ControlMover
{
    public enum Direction
    {
        Any,
        Horizontal,
        Vertical
    }

    public static void Init(Control control)
    {
        Init(control, Direction.Any);
    }

    public static void Init(Control control, Direction direction)
    {
        Init(control, control, direction);
    }

    public static void Init(Control control, Control container, Direction direction)
    {
        bool Dragging = false;
        Point DragStart = Point.Empty;
        control.MouseDown += delegate(object sender, MouseEventArgs e)
        {
            Dragging = true;
            DragStart = new Point(e.X, e.Y);
            control.Capture = true;
        };
        control.MouseUp += delegate(object sender, MouseEventArgs e)
        {
            Dragging = false;
            control.Capture = false;
        };
        control.MouseMove += delegate(object sender, MouseEventArgs e)
        {
            if (Dragging)
            {
                if (direction != Direction.Vertical)
                    container.Left = Math.Max(0, e.X + container.Left - DragStart.X);
                if (direction != Direction.Horizontal)
                    container.Top = Math.Max(0, e.Y + container.Top - DragStart.Y);
            }
        };
    }
}

ControlMover.Init(myControl, myContainer, ControlMover.Direction.Any);
