我有一个运行数据库的应用程序.当我在datagridview中加载表时,我的表单冻结了.如何在加载表期间确保平滑加载动画？

我为动画运行两个线程并将数据加载到表中,但动画仍然不能正常工作.

 private volatile bool threadRun;

 private void UpdateTab()
 {      
     // Create panel for animation
     Panel loadingPanel = new Panel();              
     // Label, where the text will change
     Label loadingLabel = new Label();

                     labelText = "Loading.";
                     i = 1;
                     break;
                 case 1:
                     labelText = "Loading..";
                     i = 2;
                     break;
                 default:
                     labelText …
