我在datagridview中更改了数据,提示保存成功,但重新运行后,数据仍是原来的数据,为什么呢?求大虾赐教.保存按钮的代码如下:
private void button1_Click(object sender, EventArgs e)
        {
            try
            {
                this.Validate();
                this.peopleBindingSource.EndEdit();
                this.peopleTableAdapter.Update(staffDataSet.people);
                MessageBox.Show("update successful");
            }
            catch (System .Exception ee)
            {
                MessageBox.Show("update failed");
            }
        }
