Question

我在WinForm应用程序中使用FastReport.Net作为我的报告工具。在那里，我需要动态创建一个TableObject，并使用数据源填充数据。我正在寻找一个示例C＃代码。

您可以在“表格”选项卡中找到它。以下内容非常有用：

private void Table1_ManualBuild(object sender, EventArgs e)
    {
      // get the data source by its name
      DataSourceBase columnData = Report.GetDataSource("Employees");
      // init the data source
      columnData.Init();

      // print the first table column - it is a header
      Table1.PrintColumn(0);
      // each PrintColumn call must be followed by either PrintRow or PrintRows call
      // to print cells on the column
      Table1.PrintRows();

      // now enumerate the data source and print the table body
      while (columnData.HasMoreRows)
      {
        // print the table body  
        Table1.PrintColumn(1);
        Table1.PrintRows();

        // go next data source row
        columnData.Next();
      }

      // print the last table column - it is a footer
      Table1.PrintColumn(2);
      Table1.PrintRows();
    }

private void Table1_ManualBuild(object sender, EventArgs e)
{
  // get the master data source
  DataSourceBase masterData = Report.GetDataSource("Categories");
  // get the detail data source
  DataSourceBase detailData = Report.GetDataSource("Products");

  // init the master data source
  masterData.Init();

  while (masterData.HasMoreRows)
  {
    // print first 3 rows that contains data from master data source
    Table1.PrintRow(0);
    Table1.PrintColumns();
    Table1.PrintRow(1);
    Table1.PrintColumns();
    Table1.PrintRow(2);
    Table1.PrintColumns();

    // init the detail data source. Pass masterData to allow master-detail relation
    detailData.Init(masterData);

    // print detail header
    Table1.PrintRow(3);
    Table1.PrintColumns();

    // print detail rows
    while (detailData.HasMoreRows)
    {
      // print the detail row
      Table1.PrintRow(4);
      Table1.PrintColumns();

      // go next data source row
      detailData.Next();
    }

    // print the detail footer row
    Table1.PrintRow(5);
    Table1.PrintColumns();
    Table1.PrintRow(6);
    Table1.PrintColumns();

    // go next data source row
    masterData.Next();
  }
