Hi Kayala,

Thanks for your interest in our API’s.

Aspose.Pdf for .NET does not support the feature to display/view PDF documents. However as a workaround (as implemented in HTML5 editor), we have followed the approach to Convert PDF Pages to JPEG Images and render the images inside image view control.

That will defeat the purpose of having a PDF…
The reason behind is that… After editing I would like to send back the pdf to the original location…

If that is the case does it support this operation?

Hi Kayala,

Thanks for sharing the details.

As per your requirement, I would suggest you to try using Assembly App of our sister company named GroupDocs.
