I am making a program in which there are multiple balls on same drawing surface. They are made by multiple instences of a class each drawing on the same usercontrol's drawing surface. I have added a motion capacity in them and methods to select them(multiple selct is also possible) but when i drag them there is a lot of fliker. I dont know how to implement the collusion detection properly in it. i need an adivce on how to have a smooth dragging without flicker. something like when we select multiple files in windows explorer and drag them.

If you could help me send me an email at (e-mail address removed)
