Datagridview row borders

[azrobert]

I have a datagridview on a form that I have managed to hide the row borders, In otherwords there is nothing seperating the rows or cells on each row......

I can not for the life of me find out what I set to do this!
I am trying to do something similar on another datagridview and
can not figure out what I set to do this !

Any one have an idea ?

I temp solved the problem by copying the grid without borders and replacing the other grid.... I would still like to find out how I did it. I am also interested in finding out how to add a border to select cells based on a value in a cell......
