Progress bar is stuck and stops moving when setting devexpress gridview datasource and styles

Question

private async void frmCyberSecurity_Load(object sender, EventArgs e)

{

 try

 {

     DataTable headersTable = new DataTable();

     await Task.Run(() =>

     {

         Logger.Info("frmCyberSecurity_Load starts....");

         string csvFilePath = Path.Combine(TempFolderPath, "Temp", "Master Policies.csv");

         dtMainPolicyTable = BusinessLogic.BusinessLogic.LoadCsv(csvFilePath);

         //DataTable headersTable = mainTable.Clone();

        

         headersTable.Columns.Add("Setting", typeof(string));

         // Add the rest of the boolean columns from mainTable

         foreach (DataColumn column in dtMainPolicyTable.Columns)

         {

             if (column.DataType == typeof(bool))

             {

                 headersTable.Columns.Add(column.ColumnName, typeof(bool));

             }

         }

     

           

         ReadAdmxFile.ParseAdmxFiles(admxDirectory, skippedFiles, out policies, out categories,

             out Global.DropDownList);

        

     });

     this.BeginInvoke(new Action(() =>

     {

         gridViewPolicy.BeginUpdate();

         gridControlPolicy.DataSource = dtMainPolicyTable;

         gridViewPolicy.EndUpdate();

         gridViewHeader.BeginUpdate();

         gridControlHeader.DataSource = headersTable;

         gridViewHeader.EndUpdate();

         SetGridviewStyle();

         panelProgress.Visible = false;

         progressPanel1.Visible = false;

         EnableTableLayoutPanelControls(tblMain);

     }));

     

 }

 catch (Exception ex)

 {

     Logger.Error($"frmCyberSecurity_Load \r\nMESSAGE         : {ex.Message}  \r\nSOURCE          : {ex.Source}  \r\nINNER EXCEPTION :{ex.InnerException} \r\nSTACK TRACE     : {ex.StackTrace}", ex);

 }

}

I'm facing an issue where the progress bar freezes when I set the DataSource of the grid and apply GridView styles. It only starts updating again once the data binding and styling are complete. I tried commenting out gridControlPolicy.DataSource = dtMainPolicyTable; and the progress bar runs smoothly, so the problem seems related to the data binding. I want the progress bar to run continuously on the UI while the data is being bound and styled in the background, and then stop once that operation is complete.
