My app crashes when trying to open hyperlinks in SfPdfViewer

Hello!

I'm having some issues when trying to open hyperlinks in SfPdfViewer. 

I have the 'AllowHyperlinkNavigation' property set to true and I'm also watching the 'HyperlinkClicked' event. 

The event is getting the correct uri as expected, but my app is crashing when leaving this method. 

It seems that it crashes when trying to open a Dialog. 

Is there any way I can open the hyperlink in browser just with the 'HyperlinkClicked' event, without needing this Dialog?

Let me show the error I'm getting next.

Thanks in advance,
Nilo Basilio

Hi Muralitharan,

I'm not able to reproduce the issue in this sample, somehow it works properly. However, I found this workaround for my application and it worked:

          void PdfViewerControl_HyperlinkClicked(object sender, Syncfusion.SfPdfViewer.XForms.HyperlinkClickedEventArgs args)
        {
             args.Handled = true;
        }

But there is another issue when testing other pdf, the 'HyperlinkClicked' event are not getting fired. 
I've attached the pdf in the sample, so you can test it. I'm using SfPdfViewer version 19.1.0.66.

Can you test it from your side, please? 

Thanks for the assist,
Nilo Basilio

Hi Nilo, 
 
Thanks for your update. We were able to reproduce the issue, “Hyperlinks are not working and Hyperlink clicked event is not triggered in a particular PDF document” . Currently, we are validating this issue and we will update the further details on June 14, 2021.

Hi Nilo, 
 
Sorry for the inconvenience caused. We are still validating the issue, “Hyperlinks are not working and Hyperlink clicked event is not triggered in a particular PDF document” due to its complexity and the issue is involved with one of our dependency (PDF Library). Currently we are working on this as high priority and we will update the validation details on June 16, 2021 without any further delay. 
 
Regards, 
Muralitharan K

Hello Muralitharan,

Hi Nilo, 
 
Thanks for your patience. As mentioned earlier we will provide the validation details for the issue, “Hyperlinks are not working and Hyperlink clicked event is not triggered in a particular PDF document” on June 16, 2021.

Muralitharan K

Hi Nilo, 
 
On further analysis, we found that the issue, “Hyperlinks are not working and Hyperlink clicked event is not triggered in a particular PDF document” is not a defect. The URL in the documents are not valid hyperlinks and it is just a text which contains a URL.   
   
Please refer to the below image where the document didn’t contain valid hyperlink annotations    
 
 
 
Other PDF Viewers automatically detect this text as a hyperlink, but at present, there is no support in our SfPdfViewer to automatically detect text in URL format as a hyperlink. Due to this while tapping the hyperlink the clicked event is not raised. We do not have any immediate plans to implement this feature. At the planning stage for every release cycle, we review all open features and identify features for implementation based on specific parameters including product vision, technological feasibility, and customer interest.         
          
Based on our present commitments and the above parameters, this feature is expected to be implemented in our 2021 Volume 4 main release. We will let you know when this feature is implemented.        
       
Disclaimer: The date for the feature implementation is tentative and not a commitment on our parts.         
       
You can now track the status of this feature request here,      
 
Regards, 
Muralitharan K
