Iterating through Bookmarks/FormFields

[Lagrange]

Hi,

I'm evaluating the Telerik.Windows.Documents API, to replace Aspose.NET in our app, for costs reason.

One of our main need, is to open existing .docx files, and replace all bookmark and formFields in the model, by business values.

I don't find any way to iterate through bookmarks and Fields. The EnumerateChildrenOfType is not usable, as Bookmark didn't inherit from DocumentElementBase.

Aspose allow it with "Document.Range.Bookmarks.Cast<Bookmark>()", can you provide an example or an equivalent ?

Regards,

Romain Lagrange

Hi Lagrange,

Thank you for contacting Telerik support.

The Bookmark itself is represented as a pair of BookmarkRangeStart and BookmarkRangeEnd objects. You could obtain all the BookmarkRangeStart elements using the EnumerateChildrenOfType() method:

IEnumerable<BookmarkRangeStart> bookmarks = document.EnumerateChildrenOfType<BookmarkRangeStart>();

The next snippet is demonstrating how you could insert text in a Bookmark:

BookmarkRangeStart first = bookmarks.First();
int index = first.Paragraph.Inlines.IndexOf(first);
first.Paragraph.Inlines.Insert(index + 1, new Run(document) { Text = "In bookmark" });

For more information about Bookmarks you could refer to our documentation on the matter.

The form fields are not supported in RadWordsProcessing. We have already logged this request and you could vote and subscribe to the related public item in the feedback portal in order to receive updates about any status changes on it.

Hope this information is useful.

This shows how to set text for the first bookmark. How do you iterate through all the bookmarks to insert text in each one of them?

Hello Lee,

Once you have obtained the bookmark start using the EnumerateChildrenOfType() method, you can traverse the collection and move the editor to the start/end of each bookmark and then insert the content using the methods of RadFlowDocumentEditor. I just sent a sample code in the other forum post with a similar question: https://www.telerik.com/forums/insert-a-list-at-a-specified-position.

Hope this helps.
