Custom background in control

Graphics in Windows is often more complex than we want it to be or expect it to be. It will really help if you understand how graphics in Windows works.
 
I think that what you want to do is to create a bitmap in memory and then copy the bitmap to the background in a bacground paint event. You should update the bitmap in a timer event and then after creating a new background, invalidate the control to let Windows re-paint it. I am not experienced with Windows graphics enough to help much with that, and WPF might have ways to make things easier so I apologize if I am misleading you.

Hi friend,

    Use  thread concept to change the background color simultaneously.
