GetAllBookmarks() is empty

[Joe Buckle]

Good day,

I'm trying to get all the bookmarks in a RadDocument, but GetAllBookmarks() returns an empty list. But when I try to set

RadRichTextBox.Document.ShowBookmarks to true, the bookmarks are there. Why is this so?

Thank you very much.

Hello Joe Buckle,

In order to get all Bookmarks, the document has to be measured and arranged. If you are invoking the GetAllBookmarks method before showing the document in a RadRichTextBox in the visual tree, the list will be empty. When the document is shown on screen, it is automatically measured and arranged, but if you would like to get all bookmarks before that, you have two options:

1. Measure and arrange the document explicitly:
   

   private IEnumerable<BookmarkRangeStart> GetAllBookmarks(RadDocument document)
   {
      document.Measure(RadDocument.MAX_DOCUMENT_SIZE);
      document.Arrange(new RectangleF(PointF.Empty, document.DesiredSize));
      return document.GetAllBookmarks();
   }

2. Use another method to get the bookmarks, which doesn't require a measured document, but is slower:
   

   private IEnumerable<BookmarkRangeStart> GetAllBookmarks(RadDocument document)
   {
    return document.EnumerateChildrenOfType<BookmarkRangeStart>();
   }

Please note that in the next version, the document will be measured automatically upon invocation of GetAllBookmarks (and methods with similar requirements) if it hasn't been previously.

Thank you very much. But how do I set the content of the bookmark for each option?

Hi Joe Buckle,

I am not quite sure I understand your question. Can you elaborate a little on your scenario, for example:

• Do you want to delete the bookmark and insert text in its place?
• Should the bookmarks be deleted, or you still wish to be able to navigate to them?
• Are you doing this before showing the document in the editor or after it is loaded?

There are some differences in the implementation depending on these factors and if you describe your needs in more detail, we would be able to send you a more useful example.

 All the best,
