Preview PDFs Directly in Business Central Web Client (v26)

With the release of version 26, a significant productivity boost has arrived: direct PDF attachment previews within the web client. No more downloading, opening external viewers, or switching between applications. This streamlined experience lets you access and review crucial documents instantly, right within your Business Central workflow.

What Does This Mean For You?

Imagine you’re processing a purchase order and need to quickly verify the attached vendor invoice. Previously, you’d have to download the PDF, open it in a separate application, and then return to Business Central. This process was time-consuming and disruptive.

Now, with the new preview functionality, you can:

• View PDFs directly in the FactBox: When a PDF is attached to a record (like a sales order, purchase invoice, or customer card), you can preview it instantly in the FactBox without leaving the page.
• Save time and improve efficiency: Eliminate the need for downloads and external viewers, allowing you to focus on your core tasks.
• Enhance collaboration: Quickly share and review documents with colleagues, streamlining approvals and decision-making.
• Enjoy a seamless user experience: The integrated preview functionality provides a more intuitive and efficient workflow.

How Does It Work?

The new feature leverages the browser’s built-in PDF rendering capabilities. When you click on a PDF attachment in the FactBox, the document opens directly within the Business Central web client, allowing you to:

• Scroll through pages.
• Zoom in and out.
• Search for specific text.

This feature is enabled by default in Business Central version 26. Simply open a record with a PDF attachment, and you’ll see the preview option in the FactBox.

For Developers:

• Microsoft has added the following AL methods to enable this functionality.
  • File.ViewFromStream (for Business Central online)
  • File.View (for Business Central on-premises)
