How to set 'Title' in grid cell programatically?

Please can you tell me how I can change the ‘title’ attribute of a grid cell after the data has been loaded? I want to change it so that a new ‘tool tip’ can be shown.

Thanks

You can use setAttribute() method of cell object:

grid.cellById(row_id,cell_index).setAttribute("title","new title");

Olga thanks very much for your answer. All this AMAZING STUFF is not documented anywhere. Why? So much waste of everybody’s time.
