Best aproach for me was     private void grid receptie CellFormatting object sender  DataGridViewCellFormattingEventArgs e                int X   1          foreach DataGridViewRow row in grid receptie Rows                        row Cells  NR CRT   Value   X              X

I used the solution below to export all datagrid values to a text file  rather than using the column names you can use the column index instead  foreach  DataGridViewRow row in xxxCsvDG Rows        File AppendAllText csvLocation  row Cells 0  Value    quot   quot    row Cells 1  Value    quot   quot    row Cells 2  Value    quot   quot    row Cells 3  Value   Environment NewLine
