Is there a way to turn off the gridlines in the flexgrid control? I've tried setting the color of the gridlines to the same color as the backcolor of the grid itself, which works fine, except for the fact that I change the backcolor property of entire columns at runtime. When I do this, the gridlines show up due to the color change. If it matters, I would actually like the vertical lines to stay... it's just the horizonal ones that cause a problem, but I can work around this pretty easily if there is a simple way of just turning off the gridlines entirely. I try not to post here without looking around for the answer elsewhere first, so any help would be greatly appreciated.
