Hi,
We don't have a sample that demonstrates that. You will need to handle the Grid's ClientSideCellSelected event and then update the cells accordingly. Here is a sample for handling ClientSideCellSelected event:
http://demo.essentialobjects.com/Default.aspx?path=Grid\_i1\_i11Inside the event handler you can do something like this:
Code: JavaScript
//Get the grid object
var grid = eo_GetObject("Grid1");
//Get the first row
var row = grid.getItem(0);
//Get the total of the first cell and the second cell
var total = row.getCell(0).getValue() + row.getCell(1).getValue();
//Add them together and assign to the third cell
row.getCell(2).setValue(total);
If you have a lot of data, you can also handle ClientSideAfterEdit event:

Thanks
