All controls are disabled on splitter panes

In my MFC application I used CSplitterWnd to create two panes and each pane is a CFormView dialog box. When run this GUI application the splitter is working and both panes are showing but all controls (button, edit box, combo box...) are disabled. Both dialog boxes have property of 'child' and 'no border'.

Did I miss something to enable all those conntrols on the pane view?

Thanks a lot for help.

I bet your message map isn't set up correctly.

Can you post your code?
