Edited Record Details

Hi

Can u tell me (in the beta version of 2.0) which function of the activewidget API will be invoked when a cell is edited .

Basically i need to know which cell and the record (of lets say 100 records) in the grid was edited so that i could only update the edited records.

So pls let me know the function which would return the details of the edited / changed / updated record in the grid.
