Show document comments

Some document types like Microsoft Word, Excel, OpenOffice Text and Spreadsheet may contain comments. Your requirement to include or exclude the comments in output representation of the document may vary in different situations. GroupDocs.Viewer enables you to control the rendering of document comments.
By default, comments are not rendered into the output document. The API provides RenderComments property of HtmlViewOptions (or JpgViewOptions, or PngViewOptions, or PdfViewOptions) class that enables rendering of comments.

This feature is supported for:

  • Microsoft Word documents
  • Spreadsheets
  • PDF documents
  • Presentations

The following code sample shows how to render documents with comments.

using (Viewer viewer = new Viewer("sample.docx"))
    HtmlViewOptions viewOptions = HtmlViewOptions.ForEmbeddedResources();
    viewOptions.RenderComments = true;
