I have a grid that is bound to a simple data source. Since this is a dashboard the user will not be entering information directly into the grid but I do update the grid's contents every few minutes.  When I read the new data I alter existing rows and would like to get a notification when a cell's value changes.  It seems like the AfterCellUpdate and CellChange events are only triggered by data entry into the grid and not by programmatic changes to the data source.  Is there another event I should look for or a different technique altogether I should try?
