OpenGL Rendering on Splitter Windows(CSplitterWnd))

When I use OpenGl rendering on CSplitterWnd Class having two child CView derived class, only one of them is rendered. That is there is one mainframe having CSplitterWnd object which create two by two or what else views. But only one of them is rendered. View classes is designed to create Opengl rendering environment. All the conventional initializations are done.
I hope that the problem is clear.

Please help in the name of jesus.
