Asked On June 19, 2019 07:10 PM UTC

Hi, I have a problem using the pdfviewer version 17.1.0.38

Using this version of PdfViewer for WPF, I am trying to add ink annotation to pdf. When I click the toggle button with pen, choose color and then I can draw which is ok. But whenever I save the document, ink annotations are not detected in annotations collection thus, nothing is saved. Something seems to be wrong since when I draw using ink, there are no handles allowing me to delete the annotation it seems like it is flatten by default...

I have tried using freetext, shape, highlighter, everything works fine except ink.

The odd behavior is exactly the same in the Syncfusion Control panel 17.1.0.38 PdfViewer getting started demo. 

To reproduce the problem, please see these steps:

Thanks a lot for the support

Hi, thanks for your feedback,

"Same happens in local Syncfusion demo project"
I have attached a video showing what I am saying about ink not saving.

PC is windows 10

"Test for sample solution sent by support"
Working with VS2019 changed Target .net Framework for 4.5 as per my own solution.
Changed dlls for my installation instead of 17.1451.0.38 it's 17.1450.0.38
Run project PdfViewerWPF

here second video attached. Also, test solution was run in VS Community 2017 and the odd behavior is the same as my solution in VS Community 2019

In my own solution I saw the problem because we work with the annotations. FreeTextAnnotation are listed as well as any other kind of Annotation in the page Annotations list except inkannotations using pen, we have nothing listed for that.
