ต้องสร้างรายงาน ใช้ FastReport ค่ะ แต่ไม่รู้วิธีการเรียกใช้ ค่ะ ASP.Net C#

private void Table1_ManualBuild(object sender, EventArgs e)
{
  // get the data source by its name
  DataSourceBase rowData = Report.GetDataSource("Products");
  // initialize it
  rowData.Init();
  
  // printing the table header
  Table1.PrintRow(0);
  Table1.PrintColumns();
  
  // loop through the data source rows
  while (rowData.HasMoreRows)
  {
    // printing the table row 
    Table1.PrintRow(1);
    Table1.PrintColumns();
    
    // select the next data row
    rowData.Next();
  }
  
  // printing the table footer
  Table1.PrintRow(2);
  Table1.PrintColumns();
}

        List<string> items = new List<string>();

        items.Add("1a askdfh askfhklas fh");
        items.Add("asgflaskjf laskjflasf");
        items.Add("asf asjlşfjaslfj aslşfas");
        items.Add("asfзjas lfjaslşfj salf");
        items.Add("asfasj flasjlşfj aslf");
        items.Add("asflkasjflasfjşlasdjlf");

        Reports.DetailedProductGroupList report = new Reports.DetailedProductGroupList(); //this is a class saved from a .frx file. It only contains a label that shows name of the report.
        report.RegisterData(items, "items");
        report.GetDataSource("items").Enabled = true;
        WebReport1.Report = report;
