线程不重新加载DataGridView

Question

我有一个应该由线程重新加载的DataGridView。但是当线程执行时，DataGridView会闪烁并且不会加载更改。

有趣的是，如果我在线程上尝试代码而不在线程上（在主线程上执行），DataGridView会重新加载！

这是我的代码：

 public void reloadClients(object source, EventArgs e)
            {
                //Console.WriteLine("Clients will reload.");
                dgvClientes.DataSource = null;
                loadReloadClients = new Thread(new ThreadStart(jobReloadAllClients));
                loadReloadClients.Start();
            }

            private void jobReloadAllClients()
            {
                this.Invoke((MethodInvoker)delegate
                {             
                    descricaoCliente.Text = "CARREGANDO TODOS OS CLIENTES";      
                });

                System.Windows.Forms.BindingSource bs = new BindingSource();
                bs.DataSource = clientes.allClients().Tables["Clientes"];


                this.Invoke((MethodInvoker)delegate
                {
                    descricaoCliente.Text = "Todos os Clientes";
                    dgvClientes.DataSource = bs;
                    dgvClientes.Refresh();

                });

            }

修改

我被告知在主线程上设置绑定数据源并在后台线程上加载BD数据.... Sievajet这是我到目前为止所得到的......

System.Windows.Forms.BindingSource bs;
    public void reloadClients(object source, EventArgs e)
    {
        //Console.WriteLine("Clients will reload.");
        dgvClientes.DataSource = null;
        bs = new BindingSource();
        dgvClientes.DataSource = bs;
        loadReloadClients = new Thread(new ThreadStart(jobReloadAllClients));
        loadReloadClients.Start();
    }

    private void jobReloadAllClients()
    {
        this.Invoke((MethodInvoker)delegate
        {             
            descricaoCliente.Text = "CARREGANDO TODOS OS CLIENTES";      
        });

        DataSet Setter = clientes.allClients();        
        this.Invoke((MethodInvoker)delegate
        {
            bs.DataSource = Setter.Tables["Clientes"];
            descricaoCliente.Text = "Todos os Clientes";
            //dgvClientes.DataSource = bs;
            //dgvClientes.Refresh();

        });

    }

Answer 1

我做到了......出于某种原因，我不得不释放变量bs，然后再次初始化它......现在它工作正常。

System.Windows.Forms.BindingSource bs;
    public void reloadClients(object source, EventArgs e)
    {
        //Console.WriteLine("Clients will reload.");
        bs = null;
        dgvClientes.DataSource = null;
        bs = new BindingSource();
        dgvClientes.DataSource = bs;
        loadReloadClients = new Thread(new ThreadStart(jobReloadAllClients));
        loadReloadClients.Start();
    }

    private void jobReloadAllClients()
    {
        this.Invoke((MethodInvoker)delegate
        {             
            descricaoCliente.Text = "CARREGANDO TODOS OS CLIENTES";      
        });

        DataSet Setter = clientes.allClients();        
        this.Invoke((MethodInvoker)delegate
        {
            bs.DataSource = Setter.Tables["Clientes"];
            descricaoCliente.Text = "Todos os Clientes";


        });

    }
