How can I speed up the scrolling of UserControls in a WinForms app.?
My main form has trouble scrolling quickly on slow machines--painting for each of the small scroll increments is CPU intensive.
My form has roughly fifty UserControls (with multiple fields) positioned one below the other. I’ve tried intercepting OnScroll and UserPaint in order to eliminate some of the unnecessary re-paints for very small scroll events, but the underlying Paint gets called anyway.
How can I streamline scrolling on slower machines?
