Posted on by Snow_89

Hello everyone

i have a gallery (Gallery1) connected to data source "Meshworks quality - news" to show all items.
in the gallery, you can select an item to be view´d in a display form - and in my display form i have a gallery that shows the attached file and a button. I want to be able to press the button and view the attached file in a PDF viwer.

Code for bottun on gallery: UpdateContext({ShowPopup4: true})& Set(varPDF,varThisItem.Miniature.Large)

Currently, i am able to press the button and it shows me the viwer but the the following error: Coudn´t open PDF file, make sure the PDF file is comming from a HTTPS link.

Any suggestions to how i overcome this issue?

Hi @Snow_89 ,
I tried from my end and basically it gives me different error and I can open the PDF in new tab in browser. You need to make sure that whoever access this PDF has enough permission on SharePoint library to open this PDF.
Not sure in your case. From your screenshot is it PDF or PPT? Also, if you are looking for PDF Viewer control to be used in your production app, then I would not recommend to use because it is still in experimental phase even Microsoft recommend the same.

As a alternative, you can use iframe PCF component for your requirement. Please check https://pcf.gallery/iframe-pcf/ which can solve your purpose.
