Programmatically output a Report Book to PDF

[steven schmalfeld]

I have seen the article on how to export to pdf without going through the viewer, but it does not seem to aply to a report book (it may just be me :))

Could I have an example where several reports are added to a report book and then the report book is sent directly to PDF?

Hello Steven,

The ReportBook object is the same as the Report object. The ReportBook is treated as a single document on display, export, print.

Please check the ReportBook example in the local demos installed by default under C:\Program Files (x86)\Telerik\Reporting Q1 2016\Examples.
If you want to create the ReportBook at run-time and export it programmatically, test the following approach:

//http://docs.telerik.com/reporting/designing-reports-general-explanation
ReportBook reportBook = new ReportBook();
reportBook.Reports.Add(new TableOfContentsReport());
switch (DateTime.Now.DayOfWeek)
{
   case DayOfWeek.Saturday:
   case DayOfWeek.Sunday:
        reportBook.Reports.Add(new WeekendReport());
        break;
   default:
        reportBook.Reports.Add(new WeekdayReport());
        break;
}
reportBook.Reports.Add(new GlossaryReport());
reportBook.Reports.Add(new IndexReport());

//http://docs.telerik.com/reporting/programmatic-exporting-report
Telerik.Reporting.Processing.ReportProcessor reportProcessor =
    new Telerik.Reporting.Processing.ReportProcessor();

// set any deviceInfo settings if necessary
System.Collections.Hashtable deviceInfo =
    new System.Collections.Hashtable();

//wrap the document in a report source
//http://docs.telerik.com/reporting/report-sources
 var IRS =  new Telerik.Reporting.InstanceReportSource();
 IRS.ReportDocument = reportBook;

Telerik.Reporting.Processing.RenderingResult result =
    reportProcessor.RenderReport("PDF", IRS, deviceInfo);

string fileName = result.DocumentName + "." + result.Extension;
string path = System.IO.Path.GetTempPath();
string filePath = System.IO.Path.Combine(path, fileName);

using (System.IO.FileStream fs = new System.IO.FileStream(filePath, System.IO.FileMode.Create))
{
    fs.Write(result.DocumentBytes, 0, result.DocumentBytes.Length);
}

Let us know if you have any further questions.

Thank you this was helpful I am able to fix the issue, but one issue I am observing;

Telerik.Reporting.XmlSerialization.ReportXmlSerializer xmlSerializer can't Deserialize Trbp files. 

I had to manually open trbp files and read definition xml file to extract trdp files and add it to reportbook.

Then I am able to export PDF in the backend.

 

 //    Telerik.Reporting.XmlSerialization.ReportXmlSerializer xmlSerializer = new Telerik.Reporting.XmlSerialization.ReportXmlSerializer();
 //    reportBook = (Telerik.Reporting.ReportBook)xmlSerializer.Deserialize(streambook);
 //}
 //foreach (var item in reportBook.Reports)
 //{
 //    MemoryStream ms1 = new MemoryStream();
 //    using (FileStream file = System.IO.File.OpenRead(item.Report.DocumentName))
 //    {
 //        file.CopyTo(ms1);
 //    }

 //}

 

using (var zip = new ZipArchive(streambook, ZipArchiveMode.Read))
{
    var entr = zip.Entries.Where(x => x.Name.StartsWith("definition")).FirstOrDefault();
    var audit = zip.GetEntry("definition.xml");
    StreamReader reader = new StreamReader(entr.Open());
    string text = reader.ReadToEnd();
    XmlDocument doc = new XmlDocument();
    doc.LoadXml(text);

 

.......

Hello Ajay,

The Report Book (.trbp) extension is an archive so in order to create a Telerik.Reporting.ReportBook object, you may use the ReportPackager class.

Please see the examples in the Packaging Report Definitions Explained - Telerik Reporting article for more details.
