DataRow.ItemArray creates a new array on the fly that contains all fields. So when you modify this array you won't modify the DataRow itself. You should use the DataRow indexer:

row[17] = ss;

You can use ItemArray when you need all objects in an array or when you want to assign the whole row's fields at once by assigning an array to this property.
