If you want to draw on a child panel, handle the Paint event of the child panel and do the drawing there. That way, your drawing gets done every time the panel paints itself.

Just in case you have not yet discovered how to do this:

1. Select the child panel in the designer
2. Bring the Properties Window into view
3. On the toolbar at the top of Properties Window, click the Lightning Bolt button, this will switch to events view
4. Look down the list, find Paint and double-click it. This will put a Paint event handler stub in your code file
5. Put your code in there.

Good luck!

I want something where the GUI alone remember all that has already designed and I would add only the new figure by the code . This way I can read from the file one figure at the time and add it to the plan to put all figures.
Thank you...
