What we do is a) create a form method that sets the relevant tooltips, and b) in the afterrowcolchange event of the grid, and any other events what would change the dynamic setting, call that method. Not fancy, works.

Note: SP2 has a bug where tooltips don't appear in grids. We had to downgrade to SP1, since this is essential functionality in our app. The tooltips are multi-line descriptions of sku and quantity, and change with each line. They are used quite often by users as a double-check while in that particular grid.
