Hi,
Advised you to manipulate the changes rather updates in your grid DataSource, then rebind it in your grid. as i see in your code surely 'You are updating the last row in your grid'...

Al is right.
On the rebinding of your grid the calculated values will be lost as the data is refetched from the data source.
Therefore you need to keep some sort of dictionary of the data you have "collected" ie the quantity variables associated with a key value from the grid.

Then fetch your source data, loop through the objects find the ones that have your key values and update the datasource and rebind.
