Hello,
I believe what you are looking for is the client-side object model of the grid (client-events) documented here:
http://help.infragistics.com/Help/NetAdvantage/NET/2008.3/CLR3.5/html/WebGrid_Client_Side_Events_CSOM.html
and BeforeEnterEditMode for focus and BeforeExitEditMode for blur. Using the parameters of the events you can get the cell and get its index and perform custom logic as needed.
