What I have
dv2.RowFilter = "[Supplier Name] LIKE '"+FilterByBox.Text+"*'";
So I need something like dv2.RowFilter = firstColumn + " LIKE '"+FilterByBox.Text+"*'";
but I don't know what the first column would be called or how to grab it and set it as a variable.
If you know the row, you can call:
dv2.Rows[rowIndex].Cells[0].Value.toString().I hope I understand it correctly.
