Connecting to Data from Code
Unsere Beispiele der Projekte und Berichtsvorlagen helfen Ihnen, die Grundlagen der Arbeit mit unserer Software zu erlernen.Dieses Beispiel ist veraltet, checken Sie viele anderen aktualisierten Beispiele in dieser Kategorie aus.This sample project demonstrates how to connect to data from the code. First, let's connect to data for the viewer:
Use
After that, load data from the XML file using
Now, let's try with Designer:
First, load the report template:
After that, get a preview report and delete all connections in the report template:
Then, load data from the XML file:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Viewer.aspx.cs" Inherits="Connect_to_Data_from_the_Code.Viewer" %>
<%@ Register assembly="Stimulsoft.Report.Web" namespace="Stimulsoft.Report.Web" tagprefix="cc1" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<cc1:StiWebViewer ID="StiWebViewer1" runat="server"
OnGetReport="StiWebViewer1_GetReport" />
</form>
</body>
</html>Use
Load() method to load the report template and delete all connections with Clear():
protected void StiWebViewer1_GetReport(object sender, StiReportDataEventArgs e)
{
// Loading the report template
var reportPath = Server.MapPath("Reports/SimpleList.mrt");
var report = new StiReport();
report.Load(reportPath);
// Deleting connections in the report template
report.Dictionary.Databases.Clear();
...After that, load data from the XML file using
ReadXml() and register it in the report with RegData():
...
// Loading data from the XML file
var dataPath = Server.MapPath("Data/Demo.xml");
var data = new DataSet();
data.ReadXml(dataPath);
// Registering data in the report
report.RegData(data);
// Syncing the data structure, if required
//report.Dictionary.Synchronize();
e.Report = report;
}Now, let's try with Designer:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Designer.aspx.cs" Inherits="Connect_to_Data_from_the_Code.Designer" %>
<%@ Register assembly="Stimulsoft.Report.WebDesigner" namespace="Stimulsoft.Report.Web" tagprefix="cc1" %>

<cc1:StiWebViewer ID="StiWebDesigner1" runat="server"
OnGetReport="StiWebDesigner1_GetReport"
OnPreviewReport="StiWebDesigner1_PreviewReport" />
</form>
</body>
</html>First, load the report template:
protected void StiWebDesigner1_GetReport(object sender, StiReportDataEventArgs e)
{
// Loading the report template
var reportPath = Server.MapPath("Reports/SimpleList.mrt");
var report = new StiReport();
report.Load(reportPath);
e.Report = report;
}
...After that, get a preview report and delete all connections in the report template:
...
protected void StiWebDesigner1_PreviewReport(object sender, StiReportDataEventArgs e)
{
// Getting a preview report
var report = e.Report;
// Deleting connections in the report template
report.Dictionary.Databases.Clear();
...Then, load data from the XML file:
...
// Loading data from the XML file
var dataPath = Server.MapPath("Data/Demo.xml");
var data = new DataSet();
data.ReadXml(dataPath);
// Registering data in the report
report.RegData(data);
// Syncing the data structure, if required
//report.Dictionary.Synchronize();
