    I would like to make page 1 of my PDF to "fit" to my container size.

    Is there a way to do this?

    Hi Kellie,

    RadPdfViewer uses the size that is set in the PDF file. The only way to change this behavior is to zoom in/out the content using the ScaleFactor property.
    Furthermore, RadPdfViewer does not fit to its parent's size and you should be careful when you are trying to use it in a container element. 

    All the best,

    I'd sure like to see this as an enhancement.  While we can do the calculations to determine the viewer size and compare to the PDF size and set the scale factor to fit.

    Hello Anna Katrina,

    Thank you for contacing us.

    The current version of RadPdfViewer allows you to achieve the desired behaviour through the following approaches:
    • You may use the ScaleMode property of RadPdfViewer to specify whether you want to fit to width, fit to page or use the default non-fitting behaviour.
    • You may bind two buttons in the UI to FitToWidthFixedDocumentPagesPresenterCommandDescriptor and FitToPageFixedDocumentSinglePageViewPresenterCommandDescriptor commands. You can see how exactly you can achieve this in the code of our PdfViewer online example.

    I hope this is helpful. If you have other questions please contact us again.
