Hi Venkitakrishnan,
Thank you for contacting support. We don’t provide UI document editor control/tools, etc. Our Group Docs brand may help you in this regard. It has the support of .NET Viewer which allows to view all your listed document formats within the web applications ([help topics](http://www.groupdocs.com/docs/display/viewernet/Home)
). It also offers .NET APIs to annotate and export annotated documents ([help topics](http://www.groupdocs.com/docs/display/annotationnet/Home)
). You may also contact with the Group Docs support representative by posting in the appropriate Group Docs forum.
Please let me know using GroupDocs.Annotation for .NET , can I add annotation in the GroupDocs.viewer for .NET.
My requirement is for a viewer that support annotation and following document formats.
1. MS Office [Word, Excel, Powerpoint] 2007,2010,2013 and 2016
2. MS Visio files - 2007,2010,2013 and 2016
3. PDF, JPEG, PNG, JPG, TIFF,GIF and BMP Formats
4. Auto cad drawings .
Using GroupDocs.Annotation for .NET can I add the annotation for the above mentioned document formats. Documents will be opened in the GroupDocs.Viewer.
Regards,
Hi Venkitakrishnan,
