Tony,
Thankyou for replying… I am posting two links:
1. This is my grid instantiation and binding

2. This is the JSON i am passing to the grid via the webservice success

Please let me know if there is anything else that might help!
edit: I know there are no widths on the columns, i forgot I had taken them out while i was trying to figure out the problem.
