How do i get row data

If i select any row and if i want the all data belongs to that row than how can i get?
Do you any idea how to update the database if i edit any cell in grid using coldfusion.
Thanks

Please, try to use the forEachCell iterator:
myGrid.forEachCell(rId,function(cellObj,ind){
var val=myGrid.cellById(rId,ind).getValue()
});
