I have a problem printing all the documents that I bring to the GRID when they end in -1 example (collection789-1) you should not print that and jump to the one that follows.
private void button2_Click_1(object sender, EventArgs e)
{
r = new imprimirmanifiesto();
int pos = 0;
//bool a = true;
for (int row = 0; row < dataGridView1.Rows.Count; row++)
{
r.imprimir(dataGridView1.Rows[pos].Cells[1].Value.ToString());
}
}
