In my gridview, I set GridLinesVisibility to "None". When the grid is displayed, there is no gridline displayed. But as I scroll the grid, horizontal grid lines appear. I noticed that if I change the grid theme to default "Office_Black", it works fine. If I change it to any other theme, horizontal gridlines appear as I scroll.
