>Can anyone tell me if it is possible to set ReadOnly property of the grid on the row level ? I want all records in the grid where column ccode='B' to be read only so users can only view the numbers with this ccode and not change them.

Interesting situation. No, there's not a row-level read-only. However, you might experiment with setting the read-only property in the AfterRowColChange() method.
