    We've come across a few documents that when loaded into the winforms pdf viewer, it shows as a blank page.  Looking online, the most likely reason is due to unsupported features in the document.  We currently like using the telerik control over just a web browser because we can load the pdf's into the UI straight as a stream, rather than saving the document to file first, so don't want to go back to the webbrowser if we don't have to.   Were wondering if we could have both the telerik control and a web browser overlaid on top of each other and show one vs the other depending on whether the telerik control can render it or not, but have not been able to find any property of the telerik control that would let us know it couldn't render it properly.  Is there a property that anyone is aware of to detect this?

    Hello Ryan,

    Thank you for writing.

    In our online documentation, we have a list with the unsupported by the pdf engine features: The described scenario could work in case you are familiar with the type of the document you are about to open, however, there is no such property.

    We are going to need the problematic pdf files in order to perform further investigation. Please note that attachments are not allowed in forum posts, so you have two options either opening a support ticket or uploading them some cloud storage and sending me the link.

    I hope this helps. Should you have further questions please do not hesitate to write back.
