Locking rows in Datasheet view

[Massoud]

Hi every body.
Is there any way so we can lock one or some of the rows of a form which is viewed as a datasheet, depending on the value of one of the fields (or change other properties such as text color) ?
I have to do this in Access97. But if it's impossible in 97 please let me know in other versions.
Thanks

So it seems there is no way to change the color of some specific row.
