Update a single cell in a Flash data grid component

Hi,

I’ve been working with the flash data grid component, and I want to update just one cell in the data grid without updating the entire dataset. I haven’t found anyway to do this and the object inheritance makes it really difficult to track down properties of specific child elements. Here’s a snippet i use to get data from a specific data cell:

var cellData:String = _currentPlaylistDataGrid.columns[0].itemToLabel(_currentPlaylistDataGrid.getItemAt(_currentSlideID));

What’s the best way to do this? It’s NOT on a click event or interactive event.
