You can't - you really need to draw this using graphics methods, preferably in the Paint event handler for the form or a container such as a Panel.

There is no standard control which just draws a line and which "follows" your controls as they potentially move around.

Thanks,but I don't know how do that!
Can you give me an example?
For example draw a line between two points (10,10) and (30,30).

Depends what language you use, but...
Handle the Paint event for a panel (or a form) and use the supplied graphics context:
e.Graphics.DrawLine(Pens.Red, 10, 10, 30, 30);
If you look at the examples in the MSDN documentation it'll help:
