C# DataGridView 刷新导致界面卡顿解决办法

public FrmSearch()
        {
            //设置窗体的双缓冲
            this.SetStyle(ControlStyles.OptimizedDoubleBuffer | ControlStyles.ResizeRedraw | ControlStyles.AllPaintingInWmPaint, true);
            this.UpdateStyles();

            InitializeComponent();

            //利用反射设置DataGridView的双缓冲
            Type dgvType = this.dataGridView1.GetType();
            PropertyInfo pi = dgvType.GetProperty("DoubleBuffered",
                BindingFlags.Instance | BindingFlags.NonPublic);
            pi.SetValue(this.dataGridView1, true, null);
        }
