This is an FYI...
I've had a problem with buttons disappearing when using CFormView. The same problem as discussed in the knowledgebase link below.

I found that doing the following will work around the issue:
- We had to select all of the controls (Ctrl+A) in the dialog.
- Shift + left click to unselect the NI buttons that were not working properly.
- Press the delete button
- Ctrl+Z to undo. (make all of the controls re-appear)
- Test this by pressing CTRL+T to test the dialog or run your application.
I hope this helps!
