WebFrame Widget only shows first page of PDF on iPad Body

Hi Community,

  I am using the WebFrame widget in a ThingWorx Mashup to display PDF files. On desktop browsers it works completely fine — I can scroll through and see all pages of the PDF.

 

However, on the iPad, if I open a PDF that has more than one page, only the first page is displayed. When I scroll down, no further pages are shown (it looks like the PDF is cut off).

 

Has anyone faced this issue before?

  • Is there any workaround / configuration needed to properly display multipage PDFs on iPads?

 

I have already tried different browsers on ipad. result is same.

Thanks in advance for your help!

I identified a simple solution to this issue that eliminates the need to purchase an additional ThingView widget.

Instead, a Navigator function can be created directly within the Mashup. While configuring the Navigator, select the “Redirect to URL” option from the dropdown menu. After creating the Navigator, assign the download link of the PDF file to the URL property.

With this approach:

  • When the file is opened on an iPad, it opens in a new browser tab, allowing the PDF to be scrollable and function as expected.

  • When the file is opened on a PC, the file is downloaded automatically.

To further enhance this solution, I developed a small ThingWorx widget extension that detects whether the Mashup is opened in a desktop browser or on a mobile/iPad device. The extension returns a Boolean value (true/false) depending on the device type.

Based on this detection:

  • On an iPad, the PDF opens in a new tab for proper scrolling.

  • On a PC, the PDF is displayed directly within the Mashup using the WebGL widget.

I have attached the extension for reference.

    That's an IPad problem, not a ThingWorx problem.
