Have you noticed in Excel, you can drag the mouse across a column of numbers and the total of the numbers will appear at the bottom right of the excel page?

YOu can also drag across a column of cells in the MSFlexgrid, but I don't know how to show a total. It isn't mouse down, because that would only show the first cell (I think) and the one in excel updates as the mouse moves over each new cell, so it must be some sort of mousemove event or cell select event.

has anybody done this before?

Thanks
