I am trying to develop a document preview feature with Syncfusion controls. My current approach is using PDFViewer to display PDFs. For office files I use the according IO-libraries (DocIO, XlsIO, ...) to convert these files to PDFs which I display in PDFViewer again. This is very slow for large files for obvious reasons. What would be the best general approach to create a document preview (I don't require implementation details, just which controls to use, etc.)? I would prefer using native controls for each file format without converting the files, but as I understand there are only controls for PDFs and spreadsheets? Is that correct? Thank you very much in advance!
