Implementing annotations for FixedDocuments shown in DocumentViewer

Implementing annotations for FixedDocuments shown in DocumentViewer

  You cannot select text within a text block. You might want to use a Figure/Floater/readononly textbox instead of it if selection is needed.

  Hi,

  I could'nt figure out how to use Figure or Floater in the FixedPage so I used the read-only TextBox in the FixedPage content. Now I'm able to select the content in the read-only TextBox but the annotations are not enabled by the selection. I've given the XAML and code behind below. Same code worked well for FlowDocumentPageViewer.

  Can you please tell me what I'm doing wrong here

  Thanks
