Check if TOC is empty

[Natalie Westphal]

When creating a table of Figures and using this call: 

figuresTOC.TableOfFiguresLabel = "Figure ";

After calling UpdateDocumentFields, is there a way to check if there are any items in the Table of Figures, and to remove the table if there are no items?

Hi Natalie,

Based on the information provided, we have found that your requirement is to remove the Table of Figures from the Word document if there are no records in it. We have prepared a sample to fulfill your requirements, which is attached below.

In the sample, we followed the following steps:
1. Open the existing Word document that contains Table of Figures
2. Update the document fields
3. Retrieve the Table of Figures from the Word document
4. Remove the Table of Figures if there are no items in it
5. Save the Word document.

During the removal process, we followed these steps:
1. Iterate through the items from the Table of Figures, starting from the first item to the last item.
2. Obtain the list of text ranges in each paragraph
3. When reaching the last item, check if the list of texts contains any values in the Table of Figures. If not, return null; otherwise, return the last item.
4. If the last item is obtained, add a bookmark at the beginning and end of the Table of Figures.
5. Delete the content within the bookmark.

Regards,
Sneha.

Is it possible to simply expose the TOCEntryEntities property on TableOfContent to just check the entity count? That is a crazy amount of code, in my opinion, to simply check if any items exist in the table of contents and then to delete the whole thing. 

Thanks,

Natalie

Hello,

Instead of removing the table of contents, is it possible to check the last value of a FieldSequence with a certain label to see if any values exist before creating the TOC?

Natalie,

Based on the information provided, we found that your requirement is to check if the target caption matches in the document sequence field caption name and then create a TOC for the caption. To meet your requirement, we have prepared and attached a sample in the below attachment.

In the attached sample, we have done the following things:
1 Open an existing Word document and find all SEQ fields using FindAllItemsByProperty.
2.Iterate through all SEQ fields and compare the sequence caption name with the target caption.
3. If a match is found, create and append a Table of Figures.
4. Update the Table of Contents.
5. Save the document.

Kindly refer the below documentation and GitHub samples

Dharanya.
