此示例顯示如何使用代碼中的Business Objects集合創(chuàng)建報(bào)表，Business Objects是一個(gè)對(duì)象類數(shù)據(jù)，使用它可以以不同的結(jié)構(gòu)呈現(xiàn)數(shù)據(jù)：表，列表，數(shù)組等，F(xiàn)illBusinessObject方法創(chuàng)建并填充數(shù)據(jù)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"));
}

創(chuàng)建數(shù)據(jù)，現(xiàn)在需要顯示它，首先，在dictionary中創(chuàng)建一個(gè)新的報(bào)表和數(shù)據(jù)結(jié)構(gòu)，從Business Object將數(shù)據(jù)傳輸?shù)絛ictionary：

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];
 
...

將組件添加到報(bào)表模板，創(chuàng)建bands Header，數(shù)據(jù)和頁腳，這些band用于放置帶有文本的文本框或?qū)usiness 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，您可以呈現(xiàn)報(bào)表并在查看器中顯示它（或調(diào)用報(bào)表設(shè)計(jì)器）：

...
 
    //Render without progress bar
    report.Render(false);
 
    report.Show();
 
    //For checking created report you can uncomment this line
    //report.Design();
}
