Hello, I have a problem with the rendering the PDF in local.
My SyncFusion elements are versioned 17.4.0.39.

The method "Load" returns 200 (with the pdf in json format), but it is not rendered in the viewer.

Hi Alessio, 

Thank you for contacting Syncfusion support. 

We are unable to reproduce the reported issue with the provide details. We have shared the simple sample in which we have tried to reproduce the issue in the below link, 


Note: If the document name  provided  in documentPath is not available our online PDF Viewer web service project then the document will not be displayed.  

Refer to the below KB to create PDF Viewer web service project and provide that URL to the serviceUrl property of the PDF Viewer.  


Please try this and let us know if you have any concerns on this. 

Regards, 
Akshaya

Hi,
the problem is not coming out when I point to your serviceUrl, but only when I try to read the pdf in local service url.
I have zipped the project, let me know if you can reproduce the issue.. anyway I've tried every project in your documentation about Pdf Viewer and I still have the same problem, maybe it's a version problem of  libraries.

Hi Alessio, 

Thank you for your update. 

We have analyzed the provided sample and found that Scripts and the sever side NuGets are referred in different version, so the PDF document is not rendered in PDF Viewer. We have shared the modified sample in the below link, 


Note:  
  • Kindly use Scripts, CSS and NuGet packages of same version in your project to avoid issues
  • Kindly delete bin, obj and X86 or x64 folders which contains the Pdfium assemblies and then build the project when upgraded to latest version
  • Always use CDN links with version to get the latest chages included for that specific release, because cdn links without version does not contain the latest changes.
  • Since we have implemented new features in our latest releases, kindly upgrade your controller code.

Please try this and revert us with more details if you have any concerns on this. 

Regards, 
Akshaya

Thank you, now it works correctly.
Just two questions: 
  • Always use CDN links with version to get the latest chages included for that specific release: Can you send to me the link where to get updated of new versions?
  • Since we have implemented new features in our latest releases, kindly upgrade your controller code: Again, how can i get updated on this?
In the documentation there is no way to check the version of the guide.. if there it is, I would like to know.
Thanks,
Alessio
