首先，我们需要将Flash设计器组件放在ASPX页面上并定义必要的事件处理器：OnSaveReport用于保存 表模板，而OnPreviewReport用于注册预览数据。还可以创建一个表和Web控件，允许以多种方式加载 表。
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="Load_and_Save_Report_in_the_DesignerFx.Default" %><%@ Register assembly="Stimulsoft.Report.WebDesign" namespace="Stimulsoft.Report.Web" tagprefix="cc1" %><!DOCTYPE html><html ><head runat="server"> <title>Load and Save Report in the DesignerFx</title> <style type="text/css"> .style1 { width: 80px; text-align: center; } .style2 { width: 260px; vertical-align: top; } </style></head><body> <form id="form1" runat="server"> <div> <cc1:StiWebDesignerFx ID="StiWebDesignerFx1" runat="server" visible="false" OnSaveReport="StiWebDesignerFx1_SaveReport" OnPreviewReport="StiWebDesignerFx1_PreviewReport" /> <table> <tr> <td class="style2"> <asp:Label ID="Label1" runat="server" Font-Names="Arial" Font-Size="11pt" Text='1. Choose ".mrt" file'></asp:Label><br /> <asp:Label ID="Label2" runat="server" Font-Names="Arial" Font-Size="11pt" Text='2. Click "Design" button'></asp:Label><br /> <br /> <asp:FileUpload ID="FileReport" runat="server" Font-Names="Arial" Font-Size="11pt" Width="264px" /> <br /> <br /> <asp:Button ID="ButtonDesignFile" runat="server" Text="Design" Width="141px" OnClick="ButtonDesignFile_Click" /> <br /> </td> <td class="style1"><b>or</b></td> <td class="style2"> <asp:Label ID="Label3" runat="server" Font-Names="Arial" Font-Size="11pt" Text='1. Choose Report on server'></asp:Label><br /> <asp:Label ID="Label4" runat="server" Font-Names="Arial" Font-Size="11pt" Text='2. Click "Design" button'></asp:Label><br /> <br /> <asp:DropDownList ID="DropDownListReport" runat="server" Width="250px"> <asp:ListItem Value="SimpleList.mrt"></asp:ListItem> <asp:ListItem Value="TwoSimpleLists.mrt"></asp:ListItem> <asp:ListItem Value="Invoice.mrt"></asp:ListItem> <asp:ListItem Value="Shapes.mrt"></asp:ListItem> </asp:DropDownList> <br /> <br /> <asp:Button ID="ButtonDesignServer" runat="server" Text="Design" Width="141px" onclick="ButtonDesignServer_Click" /> <br /> <td class="style1"><b>or</b></td> <td class="style2"> <br /> <br /> <br /> <asp:Button ID="ButtonDesignNew" runat="server" Text="Design New Report" Width="157px" onclick="ButtonDesignNew_Click" /> </td> </td> </tr> </table> </div> </form></body></html>
在下一步中，创建按钮三个单击处理程序，以多种方式加载 表模板。该ButtonDesignFile_Click方法加载从本地计算机的 表中，ButtonDesignServer_Click方法从列表加载selecter 表和ButtonDesignNew_Click方法创建新的 表模板。
protected void ButtonDesignFile_Click(object sender, EventArgs e){ if (FileReport.PostedFile != null && FileReport.PostedFile.FileName.Length > 0 && FileReport.PostedFile.InputStream != null) { StiReport report = new StiReport(); report.Load(FileReport.PostedFile.InputStream); StiWebDesignerFx1.Design(report); }}protected void ButtonDesignServer_Click(object sender, EventArgs e){ if (DropDownListReport.Text != null && DropDownListReport.Text.Length > 0) { string applicationDirectory = HttpContext.Current.Server.MapPath(string.Empty); string reportFileName = applicationDirectory + "\Reports\" + DropDownListReport.Text; StiReport report = new StiReport(); report.Load(reportFileName); StiWebDesignerFx1.Design(report); }}protected void ButtonDesignNew_Click(object sender, EventArgs e){ StiReport report = new StiReport(); StiWebDesignerFx1.Design(report);}
该StiWebDesignerFx1_SaveReport方法通过点击Flash设计的保存按钮调用。在此方法的参数中，将传递 表模板对象。您可以将此 表模板保存到文件，将数据库保存为打包字符串或使用其他方式保存。您还可以设置保存 表后将在设计器中显示的错误代码或字符串消息。
protected void StiWebDesignerFx1_SaveReport(object sender, StiSaveReportEventArgs e){ // Web Designer return StiReport object in the e.Report property var reportString = e.Report.SaveToString(); // You can set the error code which will be displayed by the designer after saving // -1: default value, the message is not displayed // 0: display 'Report is successfully saved' message //e.ErrorCode = 1; // Also you can set the custom message, it will be displayed after saving e.ErrorString = "Your report has been saved.";}
如果需要为 表预览注册一些数据，则应定义StiWebDesignerFx1_PreviewReport方法。在此方法中，您可以加载和注册必要的数据集，例如加载样本 表的XML数据。
protected void StiWebDesignerFx1_PreviewReport(object sender, StiReportDataEventArgs e){ string applicationDirectory = HttpContext.Current.Server.MapPath(string.Empty); DataSet data = new DataSet(); data.ReadXml(applicationDirectory + "\Data\Demo.xml"); data.ReadXmlSchema(applicationDirectory + "\Data\Demo.xsd"); e.Report.RegData(data);}
示例代码的结果如下图所示：
