Which event occurs if PdfViewer failed to load a documentPath?

[Nga]

Hi,

When I set documentPath with a Pdf url which no longer exists and the serviceUrl throws error, the PDF viewer shows loading icon forever. How to detect if PdfViewer failed to load a documentPath? I would like to show an information message to end user.

Thanks,
Nga

Hi Nga, 

 

Thank you for contacting Syncfusion Support. 

 

We have internally handled the error on loading the PDF document which no longer exists in the provided document path from the latest Essential Studio (15.2.0.40). The “documentUnload” event will be triggered because we have internally called unload method if the loaded PDF document does not exist in the document path. So, we request you to upgrade to our latest Essential Studio (15.2.0.40) to use the above API and you can download the same from the below link.

Also, we have provided the sample for your reference in the following location.

Hi,

I am using npm syncfusion-javascript 15.2.41. It shows error 500 (Internal Server error) on the api/PdfViewer/Load but the documentUnload event did not work.
