I have a Circle and a Line control. Circle control’s OnPaint draws a circle and Line control’s one draws a line. These two controls are contained in another control (DrawingControl). I need to put a Line over a Circle, but Circle’s background deletes the Line. I tried enabling transparency and overriding Circle’s OnPaintBackground method, but it doesn’t seem to work. Do you have any ideas? Thanks.
Does this tutorial help? It consists of three steps: Enabling transparency, overriding OnPaintBackground and overriding OnMove
