c# editing proprieties of graphics drawn on picture box

I was wondering how i would impletment a feature to my program that would allow me to edit the properties of a drawn graphic. atm if i press on my picture box it just creates another drawing but i want it to allow me to keep doing that unless u press on a already existing drawing and i want it to allow me to change the properties using the side controls. sorry english is my 2nd language so parden my bad grammar
