Please look at bookmark's Action and Destination properties here: https://pdfium.patagames.com/help/html/39813c60-72f9-1565-4e1f-0de959822d66.htm

The destination contain the PageIndex property, so you may call PdfViewer.ScrollToPage(destination.PageIndex).

Code:

if (Bookmark.Action != null)
	ProcessAction(Bookmark.Action);
else if (Bookmark.Destination != null)
	ProcessDestination(Bookmark.Destination);

Code:

private void ProcessAction(PdfAction pdfAction)
{
	if (pdfAction.ActionType == ActionTypes.Uri)
		Process.Start(pdfAction.ActionUrl);
	else if (pdfAction.Destination != null)
		ProcessDestination(pdfAction.Destination);
}

Code:

private void ProcessDestination(PdfDestination pdfDestination)
{
	ScrollToPage(pdfDestination.PageIndex);
	Invalidate();
}

Code:

_bookmarksViewer.AfterSelect += _bookmarksViewer_AfterSelect;


Code:

private void _bookmarksViewer_AfterSelect(object sender, TreeViewEventArgs e)
{
	var node = e.Node as BookmarksViewerNode;
	if (node == null || node.Bookmark == null)
		return;

	if (node.Bookmark.Action != null)
		ProcessAction(node.Bookmark.Action);
	else if (node.Bookmark.Destination != null)
		ProcessDestination(node.Bookmark.Destination);
}


BTW, you can do the following:
Code:

pdfViewer1.BookmarksViewer = bookmarksViewer1

that's all

var node = e.Node as BookmarksViewerNode;

it seems to be not possible, visual studio says it's not possible because its level protection "bookmarksviewermode"

if you are using bookmark viewer provided by sdk then you need the following only

Code:

pdfViewer1.BookmarksViewer = bookmarksViewer1


PdfViewer implements the scroll to page on click on a bookmark functionality by default.

BookmarksViewer code on WinForms is very simple. There are literally a few lines of code. Therefore, you can easily implement it in the WPF yourself, using any standard control suitable for your application. Source code can be found here: https://github.com/Patag...aster/BookmarksViewer.cs
