>>>No... I mean the user will input whatever after the prefix (in C1 on the grid), i.e. user won't input the prefix, just the text after the prefix, and after the input is accepted, the grid will display it with a dummy prefix (thus won't change the actual value inputed by user). The underlying field value will remain whatever inputed by user... and whether or not the prefix will be added is depending on the value of another field in the same record.

Yes, agree - I made several searches on this problem already, but so far came up with nothing.

BTW, I have some ideas on your other problem too, but I forgot the code and was unable to find the thread. You need to search on the way to hide/restore standard toolbars and I believe it would give you an idea to solve your problem.
