经小弟验研总结如下,可以在datagridview  CellValidating 事件里写入如下方法:      
private void dataGridView1_CellValidating(object sender, DataGridViewCellValidatingEventArgs e)
        {
            int newInteger;
            if ((!int.TryParse(e.FormattedValue.ToString(),out newInteger) && !(dataGridView1.CurrentCell.EditedFormattedValue.ToString() == "")) || ((newInteger < 0) && !(dataGridView1.CurrentCell.EditedFormattedValue.ToString() == "")))
            {
                MessageBox.Show("录入数量:“"+dataGridView1.CurrentCell.EditedFormattedValue.ToString()+"”出错,必须为整数!");
                e.Cancel = true;
            }

        }
//有新的高招请各位过路大侠留下代码,共同学习!
