Preview PDF

[maemaemae]

When I print the PDF directly to the default printer.

pdf.PrintSettings.PrinterName = print(1)
pdf.PrintSettings.PrintController = New StandardPrintController()
pdf.Print()

I want to preview the PDF.How do I code it?

We have successfully implemented the preview feature, and I’m glad to see it working properly.
However, I’ve found that navigating between pages is still a bit difficult. Would it be possible to enable page scrolling using the mouse wheel?
If that’s not feasible, would it be possible to make the page navigation buttons larger?

Hello，

The print preview mentioned above uses the .NET native PrintPreviewControl control. Its internal UI cannot be customized by our product, and the control itself does not provide direct properties to implement mouse scrolling or modify button sizes.

If you have any further questions, please feel free to let us know.

Thank you for your explanation regarding the PrintPreviewControl.

I understand that the control’s internal UI cannot be customized and that it does not support mouse wheel scrolling or button resizing directly. Thank you for clarifying this.

As navigating between pages is still a bit difficult, I was wondering if there might be any possible workarounds or alternative approaches to improve this aspect of the user experience.

Please let me know if any further input is needed from my side.

Thank you for your understanding.

Currently, there are no available methods to optimize the navigation functionality when using Spire.PDF.

For an enhanced preview experience, we recommend using our Spire.PDFViewer https://www.e-iceblue.com/Download/download-pdf-viewer-for-net-now.html. This product not only supports print preview functionality but also enables scrollable preview with more intuitive navigation.

To integrate Spire.PDFViewer into your project , please refer to our integration guide:

Should you require any assistance with the implementation, please don't hesitate to contact us.
