No Pdf render in F.E after PdfViewerController.Load method

[Alessio]

Hello, I have a problem with the rendering the PDF in local.

I used this guide : https://ej2.syncfusion.com/javascript/demos/#/material/pdfviewer/default.html

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,

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.

I've uploaded the .zip project

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, 

https://www.syncfusion.com/downloads/support/directtrac/general/ze/PdfViewer_WebAPI_Service-1363607987539352275  

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,

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
