DataGridView中的数据在新增数据后如何刷新呢——这样就可以看到这个新增的数据了

Question

这些代码写在窗体的按钮的事件处理程序中
private void button3_Click(object sender, EventArgs e)
{
try
            {
                
                string temp = "insert into [user] ([username], [password], [email]) values ('a','b','c') ";
                this.oleDbConnectionTest.ConnectionString = this.mycon;
                this.oleDbConnectionTest.Open();
                MessageBox.Show(temp);
                oleDbCommandTest.CommandType = CommandType.Text;
                oleDbCommandTest.CommandText = temp;
                oleDbCommandTest.Connection = oleDbConnectionTest;
                oleDbDataAdapterTest.InsertCommand = oleDbCommandTest;
                oleDbDataAdapterTest.InsertCommand.ExecuteNonQuery();
                oleDbDataAdapterTest.Fill(this.DataSetTest);
                ///刷新的代码，我不会写。谢谢。
                this.oleDbConnectionTest.Close();
            }
            catch (Exception ee)
            {
                MessageBox.Show(ee.ToString());
            }
}
