We have a document management application where users can preview documents for which we are using GroupDocs viewer for .NET(Licensed).
We have our documents in a shared location so before previewing we download the document locally in the application location (MVC Web application) and then generate the preview. As we don’t want to keep loading up the application we delete the downloaded local copy of document in the documentLoadCompleted.groupdocs event.
The issue is zoom and Thumbnail do not work after this as I think those use the document to create the different sized images which is deleted.
Are there any methods which can be called from our code to generate all the possible zoom images and thumbnails before user actually tries for it so that we can delete the file and user zoom still works. If this is not possible then is it possible to have preview working folder as a shared location, in that case we don’t have to download local copy and there is no issue with the deletion of the document as well.
