private void userInsert()
{
    if (MessageBox.Show("Do you want to add the new  data ?", "Confirm ", MessageBoxButtons.YesNo,MessageBoxIcon.Question) == DialogResult.Yes)
    {
        cmd.Connection = con;
        cmd.CommandType = CommandType.Text;
        try
        {
            foreach (GridViewRow dRow in userDataGridView.Rows)
            {
                cmd.CommandText = string.Format(
                    "insert into users(first_name,last_name,default_rate,default_location,spi_user_id,nickname) values('{0}','{1}',{2},{3},{4},'{5}')",
