suppress repainting of dialog (including all controls inside)

i want to be able to suppress repainting of a dialog (including the repaint of the controls in this dialog), then modify some controls (while nothing being updated on the screen) and later enable repainting for the dialog. it's because there are alot of CListCtrls that are being set invisible or visible (depends) and filled. this takes a moment and i don't want to see the "progress" of repainting control for control...
how?
i tried myDialog.SetRedraw(FALSE) but this does not affect the child controls in the dialog...
calling SetRedraw(FALSE) for every child control does not seem to do the job either...
thanks,
