Exception when using UriReportSource in a c# application: Invalid URI: The format of the URI could not be determined.

[Frederic]

Hello,

I have created a simple report using the standalone report designer.
This report is saved as a .trdx file and located in the same folder as my binaries (I initially wanted it to be in a subfolder, but go the same error)

here is my code to generate  a pdf file:

UriReportSource report = new UriReportSource();
report.Uri = "KiwixInterventionSheetActions.trdx";
            
report.Parameters.Add(new Telerik.Reporting.Parameter("CustomerId", customer_id));
            
ReportProcessor reportProcessor = new ReportProcessor();
File.WriteAllBytes(target_filename, reportProcessor.RenderReport("PDF", report, null).DocumentBytes);

When I do the RenderReport, I get the exception message: "Invalid URI: The format of the URI could not be determined."
If I use a different file name, I get another exception saying that the file cannot be found, so this means that the Uri is correctly interpreted at some stage.

If I use a XmLReportSource instead and fill the Xml field from the content of the file by using following code:

XmlReportSource report = new XmlReportSource();
report.Xml = File.ReadAllText("KiwixInterventionSheetActions.trdx");

then it works, but I need to be able to support UriReportSource, because my final application uses sub-reports specified as files. Whne using the XmlReportSource, the main report works, but the pdf contains identical error message for the sub reports.

Thanks in advance

Fred

Hello Frederic,

When using one of our ReportViewer controls the base path that relative UriReportSources are resolved against is determined automatically - depending on the technology (WebForms - Virtual Directory, WinForms - Executable path, etc.) However when using the ReportProcessor directly it is up to the developer to provide an UriReportSource with absolute path. Then the directory from that uri will be used as base path and all sub report items may have relative paths - they will be converted to absolute paths using the base path.

Hope this makes sense.

All the best,
