Hi Akash,
Please refer www.syncfusion.com/library
http://www.syncfusion.com/library/default.aspx?url=gridwindows/QuerycellinfoEvent.html
QueryCellInfo is raised to provide the GridStyleInfo object for a given cell on demand, therefore is raised several times.
SaveCellInfo is raised to save the data of the cell when leaving the cell.
Regards,
Stanley
