How to go to destination page by using bookmarks of the PDF document in PdfViewer control?
At present, we do not have support for Bookmark Navigation in PDFViewer. However, the below workaround can be used to perform the navigation to that particular page using bookmarks of the PDF document.
Note: This workaround can handle only the navigation to a page. Navigation to a location/coordinates in a page is not supported.
The following code snippet explains how to perform the Bookmark navigation.
C#
/// <summary>
/// Goes to the destination page when triggered
/// </summary>
/// <param name="sender">Event Sender</param>
/// <param name="e">Contains Event data of the Item clicked</param>
private void listView_ItemClick(object sender, ItemClickEventArgs e)
{
string clickedItem = e.ClickedItem.ToString();
// Bookmark selected from the ListView
PdfLoadedBookmark bookmark = bookmarksDictionary[clickedItem];
// Destination page
PdfPageBase page;
// Checks the destion of the selected bookmark
if (bookmark.Destination != null)
{
// assigns the destination page
page = bookmark.Destination.Page;
int pageIndex = 0;
// Find the Page Number by comparing the destination page with all the
pages
foreach (PdfPageBase pageBase in ldoc.Pages)
{
// checks whether the iterated page equals the destination page
if (pageBase == page)
{
// Goes to particular page using the Page Index
pdfViewer.GotoPage(pageIndex + 1);
break;
}
pageIndex++;
}
}
}
