此示例显示如何使用代码中的Business Objects集合创建报表。Business Objects是一个对象类数据,使用它可以以不同的结构呈现数据:tables(表),lists(列表),arrays(数组)等,FillBusinessObject方法创建并填充数据集合:
private ArrayList list = null; private void FillBusinessObject() { list = new ArrayList(); list.Add(new BusinessEntity("name1", "alias1")); list.Add(new BusinessEntity("name2", "alias2")); list.Add(new BusinessEntity("name3", "alias3")); }
创建数据,现在需要显示它。首先,您应该在Dictionary中创建一个新的报表和数据结构,从Business Object将数据传输到Dictionary:
private void PrintDataGrid(DataGrid sender) { StiReport report = new StiReport(); report.ScriptLanguage = StiReportLanguageType.CSharp; //Add data to datastore report.RegData("MyList", list); //Fill dictionary report.Dictionary.Synchronize(); StiPage page = report.Pages.Items[0]; ...
然后,您需要将组件添加到报表模板。您应该创建bands Header,数据和页脚。这些band用于放置带有文本的文本框或对Business Object字段的引用:
... //Create HeaderBand StiHeaderBand headerBand = new StiHeaderBand(); headerBand.Name = "HeaderBand"; page.Components.Add(headerBand); //Create Databand StiDataBand dataBand = new StiDataBand(); dataBand.DataSourceName = "MyList"; dataBand.Height = 0.5f; dataBand.Name = "DataBand"; page.Components.Add(dataBand); StiDataSource dataSource = report.Dictionary.DataSources[0]; //Create texts Double pos = 0; Double columnWidth = StiAlignValue.AlignToMinGrid(page.Width / dataSource.Columns.Count, 0.1, true); int nameIndex = 1; foreach (StiDataColumn column in dataSource.Columns) { if (column.Name == "_ID" || column.Name == "_Current")continue; //Create text on header StiText headerText = new StiText(new RectangleD(pos, 0, columnWidth, 0.5f)); headerText.Text.Value = column.Name; headerText.HorAlignment = StiTextHorAlignment.Center; headerText.Name = "HeaderText" + nameIndex.ToString(); headerText.Brush = new StiSolidBrush(Color.MediumSeaGreen); headerText.Border.Side = StiBorderSides.All; headerBand.Components.Add(headerText); //Create text on Data Band StiText dataText = new StiText(new RectangleD(pos, 0, columnWidth, 0.5f)); dataText.Text.Value = "{MyList." + column.Name + "}"; dataText.Name = "DataText" + nameIndex.ToString(); dataText.Border.Side = StiBorderSides.All; dataBand.Components.Add(dataText); pos += columnWidth; nameIndex ++; } //Create FooterBand StiFooterBand footerBand = new StiFooterBand(); footerBand.Height = 0.5f; footerBand.Name = "FooterBand"; page.Components.Add(footerBand); //Create text on footer StiText footerText = new StiText(new RectangleD(0, 0, page.Width, 0.5f)); footerText.Text.Value = "Count - {Count()}"; footerText.HorAlignment = StiTextHorAlignment.Right; footerText.Name = "FooterText"; footerText.Brush = new StiSolidBrush(Color.LightGreen); footerBand.Components.Add(footerText); ...
在此之后,您可以呈现报表并在查看器中显示它(或调用报表设计器):
... //Render without progress bar report.Render(false); report.Show(); //For checking created report you can uncomment this line //report.Design(); }
示例代码的结果如下图所示:
