Grid Refresh Example - Yahoo Stock Market - how do I refresh part of the grid | datagrid, gridview, jquery grid examples, javascript ui

hi everyone,
This is a work in progress using this fabulous grid.
My question is:
How can I refresh only part of the grid. ie only the columns that are not fixed...so that I can double click on the code column and change the code to a new one and have it bring back that codes data. (like a watch list).

I thought I might share it with everyone... Any help in enhancing or rewriting the code in a better way is much appreciated. Also looking to be able to add and delete rows to this grid.

Thanks
Alex H
