尽管有线程，DataGridView数据加载的UI性能也很差

Question

我已经为我的datagridview创建了一个线程来提高性能 但我仍然可以看到我项目的滞后和反应迟钝。我想要的就是顺利运行。 还有一个问题，如果我的datagridview中有大量数据，我是否应该创建一个加载内容来欺骗用户？

注意看我的代码，我做对了吗？或者我应该做些更好的事情？

public studentManager()
    {
        InitializeComponent();
        ThreadStart thread1Start = new ThreadStart(LoadGrid);
        Thread t1 = new Thread(thread1Start);
        t1.Start();
    }



 public void LoadGrid()
    {
        if (radGridView1.InvokeRequired)
            radGridView1.Invoke(new Action(() =>
            {
                //For Buttons stuffs
                add.Image = Properties.Resources.adde;
                add.Enabled = true;
                delete.Image = Properties.Resources.deleted;
                delete.Enabled = false;
                update.Image = Properties.Resources.updated;
                update.Enabled = false;
                errorProvider1.Clear();

                //Datagridview
                MySqlConnection connection = new MySqlConnection(MyConnectionString);
                connection.Open();
                try
                {
                    MySqlCommand cmd = connection.CreateCommand();
                    cmd.CommandText = "Select * from studenttable";
                    MySqlDataAdapter adap = new MySqlDataAdapter(cmd);
                    DataSet ds = new DataSet();
                    adap.Fill(ds);
                    radGridView1.DataSource = ds.Tables[0].DefaultView;

                    label8.Text = "Student Information loading completed!";

                    radGridView1.Columns[0].HeaderText = "Student Number";
                    radGridView1.Columns[0].Width = 100;
                    radGridView1.Columns[1].HeaderText = "Name";
                    radGridView1.Columns[1].Width = 300;
                    radGridView1.Columns[2].HeaderText = "Section";
                    radGridView1.Columns[2].Width = 50;
                    radGridView1.Columns[3].HeaderText = "Email";
                    radGridView1.Columns[3].Width = 100;
                    radGridView1.Columns[4].HeaderText = "Course";
                    radGridView1.Columns[4].Width = 50;
                    radGridView1.Columns[5].HeaderText = "Gender";
                    radGridView1.Columns[5].Width = 150;
                    radGridView1.Columns[6].IsVisible = false;
                }
                catch (Exception)
                {
                    throw;
                }
                finally
                {
                    if (connection.State == ConnectionState.Open)
                    {
                        connection.Clone();
                    }
                }
            }));
        else
        {
            label8.Text = "Data information is loading........";
        }


    }
