GroupDocs.Viewer for .NET doesn’t support document annotation. However, you can use GroupDocs.Annotation for .NET API in order to annotate and view documents. Have a look at this open-source project.
Second option is, you can implement Annotation API along-with Viewer (add annotation at the back-end and view annotated file in the viewer application).

Okay…Thanks.like second option i need to make highlight.

Viewer already designed in an web page inside div.i have a button to select highlighted area on viewer image.i have coordinate values of the highlighted text,by using this i need to apply on original document.

Yes, you can do that. Using Annotation API you can redact or highlight text.
