I have a problem: I have DataGridView1 and when I read the database records each line should be added to a Column of my DataGridView1 . Example my DataGridView1 has the Column1, Column2, ... Column10 columns and when scanning the database I have the logs: 1,2,3 ... 20 where DataGridView1 should be fed as in the image below, anyone have any suggestions how can I do this?

AndthiswouldbemytableinthedatabasewhereIalreadymakeaqueryandgetthevalueofthecolumnFICCODImaketheconversiontointegerandthenaddittothegrid!
