The border color will be resolved to System.Drawing.Color.Black if the SelectionOverlayColor is set. If no borders are desired, this property can be set to System.Drawing.Color.Transparent.
Note: If this property is set without the SelectionOverlayColor being set, the borders will surround the selected area. If either of these properties are set, however, any selected appearances (i.e. cell, row, column) that would normally apply to the cell are now ignored.
