I have a unique requirement:

My current jQuery grid works fine. Currently I have editing enabled (Features => updating). Anyhow, I have to disable editing of a specific column once added. So basically, if someone add's a record they should be able to enter "Col A, B, C, D". However if they edit, only Columns A, B, and D should be editable.

Changing the column properties for updating to Read-Only for the column also affects adding a new row. Is there any way around this?
