@kranthireddyr,

In addition to the above reply, please also try the following code example:
C#

string dataDir = @"c:\pdf\test\";
// Change Viewer Preferences
PdfContentEditor contentEditor = new PdfContentEditor();
contentEditor.BindPdf(dataDir + "MyPdf.pdf");
int view = contentEditor.GetViewerPreference();
if (view == ViewerPreference.PageModeUseOutlines)
    Console.WriteLine("Pages view in the Navigation Panel");
else if (view == ViewerPreference.PageModeUseThumbs)
    Console.WriteLine("Bookmark view in the Navigation Panel");

We would like to request you to use below code samples in your environment and then share your kind feedback with us. You can set the bookmark pane to be visible by default while using the code snippet below:

PdfContentEditor pdfContentEditor = new PdfContentEditor();
pdfContentEditor.BindPdf(dataDir + "Jay-Test-Doc-with-Bookmarks.pdf");
ViewerPreference viewerPreference = new ViewerPreference();
pdfContentEditor.ChangeViewerPreference(ViewerPreference.PageModeUseOutlines);
pdfContentEditor.Save(dataDir + "Jay-Test-Doc-with-Bookmarks_18.3.pdf");

and you can check visibility of bookmark pane by using following code snippet:

PdfContentEditor contentEditor = new PdfContentEditor();
contentEditor.BindPdf(dataDir + "Jay-Test-Doc-with-Bookmarks_18.3.pdf");
int view = contentEditor.GetViewerPreference();
if ((view & ViewerPreference.PageModeUseOutlines) != 0)
 Console.WriteLine("Bookmark view in the Navigation Panel");
