Trial Version - version mismatch error

[MA]

Hi, 

I'm currently evaluating Telerik Reporting to see if it fits our requirements.

I'm trying to use the "Export a report to a single document to render a report"  to render a very simple report with a single "Hello World" textbox. I used the sample code in the link below.

 

https://docs.telerik.com/reporting/programmatic-exporting-report

I downloaded Telerik.Reporting from nuget.org with version: 13.2.19.1030

I however is experiencing an error once I get to the code:

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

 

Error: 

Telerik.Reporting.Xml.UnsupportedVersionException: 'Cannot read a document with the specified schema: http://schemas.telerik.com/reporting/2020/2.0.
You might be using an older version of the product.'

How should I get around this ? 

We're trying to get to a decision soon so can you please help us asap.

Thank You

Hi M A,

All the Reporting resources and assemblies that interact in a project must be of the same version. From the exception message I infer that the report you use is created with the Standalone designer version R2 2020, for example, 14.1.20.618. The schema of the designer cannot be recognized by the older Telerik Reporting version and this causes the error. You need to reference the same or higher Telerik Reporting version in your project, for example, to upgrade the Telerik.Reporting package to 14.1.20.618.

The other option is to change the schema of your report definition. You may save it as a TRDX file and manually modify the schema to 'http://schemas.telerik.com/reporting/2019/2.0' - see also XML Schema Versioning.

Hello Aqeel,

You can download an older version of Telerik Reporting from your Telerik account, here is the direct link to the download page:

Download Telerik Reporting 

From the "Version" dropdown you can choose a concrete version  - it lists the available release per your license.

I hope this was helpful. Let me know if I can assist with anything else.
