I added few extra columns, and now these 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
Apparently, CF doesn't like it when plus and minus signs are used in column.MappingName property.
