CListCtrl adding second header

I have a CListCtrl, in report view, which contains mostly numeric data. I have a CheaderCtrl at the top describing the data. I want to add a second CheaderCtrl to the bottom that will sum up or average the rows that are selected.

I already use my own derived classes of CListCtrl and CheaderCtrl and handle the OnDraw for both.

I have the starts of two possible solutions what do you like best, and what am I missing?


1
I would like to do this inside my CListCtrl because there are several places I would like to use this. The problem is forcing the CListCtrl to scroll up far enough to show all the data. I thought of adding a empty row so it would not block valid data, but that gets complicated with allowing sorting. In OnDraw I can NOT draw the last item (in the case there are fewer rows than the height of the control). It would be nice if there was a way to tell the CListCtrl not to use the bottom piece of itself to display data.

Make the CListCtrl have no Scrollbars. Can't just remove the Horizontal bar. Infact CListCtrl will not creat any headers if the LVS_NOSCROLL style is used. Have the view handle the scrolling and send messages to the CListCtrl. Not what I want to do with a CFormView with two such CListCtrls.
