I have used CScrollView for my view class in order to do scrolling in an OpenGL window. The problem is that when i scroll vertically or horizontally, the viewport does not move with the scroll bars .

Is there any method through which scrolling can be implemented in an OpenGL window so that when we scroll, it does scrolling in the same way like ordinary GDI windows.


Thank you

No, OpenGL doesnt take care about scrolling position or even windows viewport information. It has its own transformation matrices including translations (scrolling).
So, if you want to take effect, you must "synchronize" scrolling information with translation values. You have to trap scrolling events, vary transformation matrix values (x and y) and redraw opengl view.
You must use  glTranslate() function.
