Creting reports using C#

Question

Many reports, which you will create, have got a structure already known to you. But sometimes the report structure is not known beforehand. For example, you need to create a report, whose interior is configured by the user with the help of the master. In this case, the report can be created with the help of code.

Let us see how this can be done by using FastReport.Net

The report consists of one (often) or several pages having the ReportPage type. Report pages in turn, contain bands. On the band, there are report objects like "Text", "Picture" and others.

Lets look at an example of creating a report from group called products.Here is the code:

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 a 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 the 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();

And the report is ready.
