Using Graphics on added control

I need to be able to add pictureboxes at run time by adding them to me.controls. I also need to perform graphics operations on these controls but they do not have a paint event.

I am new to .net and from what I can tell graphics can only be processed in the paint event i.e you need the 'e as painteventargs'

Is there a way to process graphics (such as alpha blending) on these controls.

Thanks for your help in advance

Perhaps you'll like to have a control array: 174835
