概述：此示例項目顯示了在運行時創(chuàng)建Web報表的可能性。您只需要Web查看器即可顯示創(chuàng)建的報表，并最少創(chuàng)建報表項目的代碼。

要添加Web查看器，您可以使用以下ASPX頁面。

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Report.aspx.cs" Inherits="Runtime_Report_Creation.Report" %>
<%@ Register Assembly="Stimulsoft.Report.Web" Namespace="Stimulsoft.Report.Web" TagPrefix="cc1" %>
 
<!DOCTYPE html>
 
<html xmlns="//www.w3.org/1999/xhtml">
<head runat="server">
    <title>Runtime Report Creation</title>
</head>
<body>
    <form id="form1" runat="server">
        <cc1:StiWebViewer ID="StiWebViewer1" runat="server" />
    </form>
</body>
</html>

所有必要的操作都可以在網(wǎng)頁的Page_Load事件中完成。首先，創(chuàng)建新的報表對象，讀取數(shù)據(jù)并將其連接到報表字典。

protected void Page_Load(object sender, EventArgs e)
{
    DataSet data = new DataSet();
 
    data.ReadXmlSchema(Server.MapPath(@"Data\Demo.xsd"));
    data.ReadXml(Server.MapPath(@"Data\Demo.xml"));
 
    StiReport report = new StiReport();
    report.RegData(data);
 
    //Fill dictionary
    report.Dictionary.Synchronize();
...

然后我們需要創(chuàng)建報表組件。首先，使用將顯示標(biāo)題的Text組件將Header Band添加到報表頁面。

...
    StiPage page = report.Pages[0];
 
    //Create HeaderBand
    StiHeaderBand headerBand = new StiHeaderBand();
    headerBand.Height = 0.5;
    headerBand.Name = "HeaderBand";
    page.Components.Add(headerBand);
 
    //Create text on header
    StiText headerText = new StiText(new RectangleD(0, 0, 5, 0.5));
    headerText.Text = "CompanyName";
    headerText.HorAlignment = StiTextHorAlignment.Center;
    headerText.Name = "HeaderText";
    headerText.Brush = new StiSolidBrush(System.Drawing.Color.LightGreen);
    headerBand.Components.Add(headerText);
...

接下來，使用添加表達(dá)式的Text組件添加數(shù)據(jù)帶。此表達(dá)式組合了客戶數(shù)據(jù)源中的行號和CompanyName數(shù)據(jù)列。

...
    //Create Databand
    StiDataBand dataBand = new StiDataBand();
    dataBand.DataSourceName = "Customers";
    dataBand.Height = 0.5;
    dataBand.Name = "DataBand";
    page.Components.Add(dataBand);
 
    //Create text
    StiText dataText = new StiText(new RectangleD(0, 0, 5, 0.5));
    dataText.Text = "{Line}.{Customers.CompanyName}";
    dataText.Name = "DataText";
    dataBand.Components.Add(dataText);
...

最后，使用Text組件添加頁腳頁帶，該組件在頁面底部顯示文本。最后一個操作是將創(chuàng)建的報表分配給WebViewer，WebViewer將自動構(gòu)建和顯示它。

...
    //Create FooterBand
    StiFooterBand footerBand = new StiFooterBand();
    footerBand.Height = 0.5;
    footerBand.Name = "FooterBand";
    page.Components.Add(footerBand);
 
    //Create text on footer
    StiText footerText = new StiText(new RectangleD(0, 0, 5, 0.5));
    footerText.Text = "Count - {Count()}";
    footerText.HorAlignment = StiTextHorAlignment.Right;
    footerText.Name = "FooterText";
    footerText.Brush = new StiSolidBrush(System.Drawing.Color.LightGreen);
    footerBand.Components.Add(footerText);
 
    StiWebViewer1.Report = report;
}
