}  

private void dataGridView1_DataError( object sender, DataGridViewDataErrorEventArgs e)
{ //验证触发异常时，显示错误提示

if (!e.ThrowException && e.Exception != null)
            {
                MessageBox.Show(e.Exception.Message, "系统提示", MessageBoxButtons.OK, MessageBoxIcon.Warning);
                dataGridView1[e.ColumnIndex, e.RowIndex].Selected = true;
                dataGridView1.CurrentCell = dataGridView1[e.ColumnIndex, e.RowIndex];
                e.Cancel = true;
            }

}
