>>At the days of VFP 7 we have tricked tooltip with some faked ToolTip things. (Multiline, non limited lenght) Possibly you can found the classes on the web. For example download#9300.

>That download is very old (from 1997) so I am not sure it will work for me. I think the main problem is to show information from the row the mouse is over. Does your tooltip solve that problem? If yes and you can dig that solution, it will be great.

Somehow I mixed up Win 7 and VFP 7 :)

The only way I know of is to catch the mouse events of the header (via eventbinding?) and change the grids tooltiptext. But commonly this requieres something with setfocus and API , for all what I remember, because you will be second in row. Check the download how they do it. I also found a class here what does similar things

In general, VFP 9 is worst then VFP 8 in that. IOW: I do not use Tooltiptext on grids since we've got VFP 9 (And I was a fan of it before)
