Question

I have the following line :

if ( dataGridView1.Rows[i].Cells[0].Value.ToString().Length >= 13 ){      
                e.Graphics.DrawString
(dataGridView1.Rows[i].Cells[0].Value.ToString().Substring(0,14),
print6B, Brushes.Black, x-10, 130 + height);
                }
                else {

Because of the Substring method i get this error:
index and length must refer to a location within the string c#

What is the best method to get the first 14 characters of the string ?

It looks fine to me. Are you sure you aren’t grabbing the header row? It’s a common error when dealing with the gridview.

if (dataGridView1.Rows[i].RowType == DataControlRowType.DataRow)
{
    if (dataGridView1.Rows[i].Cells[0].Value.ToString().Length > 13)
    {
        e.Graphics.DrawString(dataGridView1.Rows[i].Cells[0].Value.ToString().Substring(0,14), print6B, Brushes.Black, x-10, 130 + height);
    }
}
