下面我们简单介绍，如何通过代码创建报表：

Report report = new Report();

// register the "Products" table

 report.RegisterData(dataSet1.Tables["Products"], "Products");

// enable it to use in a report

 report.GetDataSource("Products").Enabled = true;

// create A4 page with all margins set to 1cm

ReportPage page1 = new ReportPage();

 page1.Name = "Page1";

 report.Pages.Add(page1);

// create ReportTitle band

 page1.ReportTitle = new ReportTitleBand();

 page1.ReportTitle.Name = "ReportTitle1";

// set its height to 1.5cm

 page1.ReportTitle.Height = Units.Centimeters * 1.5f;

// create group header

GroupHeaderBand group1 = new GroupHeaderBand();

 group1.Name = "GroupHeader1";

 group1.Height = Units.Centimeters * 1;

// set group condition

 group1.Condition = "[Products.ProductName].Substring(0, 1)";

// add group to the page.Bands collection

 page1.Bands.Add(group1);

// create group footer

 group1.GroupFooter = new GroupFooterBand();

 group1.GroupFooter.Name = "GroupFooter1";

 group1.GroupFooter.Height = Units.Centimeters * 1;

// create DataBand

DataBand data1 = new DataBand();

 data1.Name = "Data1";

 data1.Height = Units.Centimeters * 0.5f;

// set data source

 data1.DataSource = report.GetDataSource("Products");

// connect databand to a group

 group1.Data = data1;

// create "Text" objects

// report title

TextObject text1 = new TextObject();

 text1.Name = "Text1";

// set bounds

 text1.Bounds = new RectangleF(0, 0,

   Units.Centimeters * 19, Units.Centimeters * 1);

// set text

 text1.Text = "PRODUCTS";

// set appearance

 text1.HorzAlign = HorzAlign.Center;

 text1.Font = new Font("Tahoma", 14, FontStyle.Bold);

// add it to ReportTitle

 page1.ReportTitle.Objects.Add(text1);

// group

TextObject text2 = new TextObject();

 text2.Name = "Text2";

 text2.Bounds = new RectangleF(0, 0,

   Units.Centimeters * 2, Units.Centimeters * 1);

 text2.Text = "[[Products.ProductName].Substring(0, 1)]";

 text2.Font = new Font("Tahoma", 10, FontStyle.Bold);

// add it to GroupHeader

 group1.Objects.Add(text2);

// data band

TextObject text3 = new TextObject();

 text3.Name = "Text3";

 text3.Bounds = new RectangleF(0, 0,

   Units.Centimeters * 10, Units.Centimeters * 0.5f);

 text3.Text = "[Products.ProductName]";

 text3.Font = new Font("Tahoma", 8);

// add it to DataBand

 data1.Objects.Add(text3);

// group footer

TextObject text4 = new TextObject();

 text4.Name = "Text4";

 text4.Bounds = new RectangleF(0, 0,

   Units.Centimeters * 10, Units.Centimeters * 0.5f);

 text4.Text = "Count: [CountOfProducts]";

 text4.Font = new Font("Tahoma", 8, FontStyle.Bold);

// add it to GroupFooter

 group1.GroupFooter.Objects.Add(text4);

// add a total

Total groupTotal = new Total();

 groupTotal.Name = "CountOfProducts";

 groupTotal.TotalType = TotalType.Count;

 groupTotal.Evaluator = data1;

 groupTotal.PrintOn = group1.Footer;

// add it to report totals

 report.Dictionary.Totals.Add(groupTotal);

// run the report

 report.Show();
