I ask this question because upon coloring the cell background with the color I needed I noticed that something looked funny. The Borderbrush was not colored. So I said ok I'll just color it and change it individually each time I move from cell to cell
but something is a miss. Once I color the Borderbrush the same as the background color you can't see it anymore. I know. Your saying duh. But really should it be that way? The borderbrush shouldn't really have it's own area from outside
a cell. It's position should be inside the cell. Because of the way DataGrid is designed it doesn't look like coloring the Borderbrush seems to be a good idea.
However. I still need to color my cells without a transparent Borderbrush that's actually visible due to the fact that you can see though it to the background.
