I added few extra columns, and now these stupid X are back but only on the first line on certain columns. By X I mean the background the cell is crossed over like a large x. I used to have this issue before and solved it by setting the alternating color to white. Nothing else has been changed aside from adding 3 extra columns to the datagrid.
Anyone knows how to get rid of them? Thanks!
PS: whoever voted it for closing should really get off the high horse and get to work
