Should I use a PictureBox or a Panel to draw on my Form?

Question

Is there a recommended one to use in order to add lines and circles, so I can build a graph? I will possibly work with background images under the graph itself.

Answer 1

Use a PictureBox - it'll be easiest to maintain the code later on. A Panel is not really useful in this case and drawing directly on the Form - while it'd work - would make it harder to make changes later on.

Just handle the Paint event of the PictureBox and do all your drawing in there.
