I have windows form, when I scroll slowly, the form and its content scrolls smoothly. However, when I drag and scroll a little faster, the controls disapper for a second and comes back. It doesn't scroll smoothly. I guess the form refreshes. I do have a lot of controls on my form. It looks a bit annoying when you see your content is gone. I do have a screenshot of the problem to show what I mean, but I can't post it here. Thanks for the help.

If it's big the computer or software may be experiencing problems attempting to keep up with the requested changes causing the screen to disappear till it can be redrawn with the new information displayed.

EveryTime you Scroll , the Form gets Painted Once Again...ALso if you use too many Controls on the form ..this is a common issue..
but yes, to some extent, the memory load on cpu also matters

Thanks for your reply. The form is actually big. It has lots of controls on it, specially nested controls and user controls. Is there a way to control the redrawing of the control?
I have sufficient amount of memory on my PC and P4 processor.
