Can no longer export reportbook to PDF - Invalid ReportSource

[Clyde]

I've just upgraded to the 611 version and I can no longer successfully build my solution. It seems that the RenderReport method will no longer accept a ReportBook parameter although all the documentation claims that it does.

My scenario is that I create a ReportBook from 3 Reports and then pass it over to the ExportToPDF method. I now get the following compile time errors.

Error    66    Argument 2: cannot convert from 'Telerik.Reporting.ReportBook' to 'Telerik.Reporting.ReportSource'   
Error    65    The best overloaded method match for 'Telerik.Reporting.Processing.ReportProcessor.RenderReport(string, Telerik.Reporting.ReportSource, System.Collections.Hashtable)' has some invalid arguments

    void ExportToPDF(string reportName, Telerik.Reporting.IReportDocument reportToExport)

    {

        ReportProcessor reportProcessor = new ReportProcessor();

        RenderingResult result = reportProcessor.RenderReport("PDF", reportToExport, null);

 

       using (FileStream fs = new FileStream(fileName, FileMode.Create))

        {

            fs.Write(result.DocumentBytes, 0, result.DocumentBytes.Length);

        }

     }

I have tried multiple ways to configure this using the ReportSource class but am unable to figure out how this works.

Your assistance, as always, is greatly appreciated.

Thanks

Hi Clyde,

Because of the new ReportSource you need to handle the ReportBook export differently. Create instance of InstanceReportSource and pass to its property ReportDocument your ReportBook. After that use the new InstanceReportSource in the place of the ReportBook.

Here is a sample:

InstanceReportSource reportSource = new InstanceReportSource();
reportSource.ReportDocument = new MyReportBook();

ReportProcessor reportProcessor = new ReportProcessor();
RenderingResult result = reportProcessor.RenderReport("PDF", reportSource, null);

We would improve the ReportBook handling for subsequent versions.
