TOC default text changes color when "Update Field" is clicked

Question

TOC default text changes color when "Update Field" is clicked

Connor Shore 50

I have a question why the color changes in a specific document when "Update Field" is clicked. Our application creates output from a template. In the download link is the template file (TocUpdateIssueTemplate.docx) and the output generated from that template (TocUpdateIssueOutput_BeforeUpdate.docx). The output visually looks identical to the template as you can see. However, if you go to the line "No table of figures entries found" and right click on it and select "Update Fields" you will notice the text changes from blue to black. The resulting docx is TocUpdateIssueOutput_AfterUpdate.docx). The ooxml of the before and after document look pretty much identical except the <w:color> element has been removed in document.xml. The weird thing is, if you do "Update Fields" in the template document, the text remains the same color and the <w:color> element is not removed in the ooxml. Is there something in the output documents that cause this to happen when update is clicked or is this a weird one off issue? Any help is appreciated. Thank you!

Hi @Connor Shore I investigated files you have shared and it looks to me that issue was caused at the code level when file(TocUpdateIssueBeforeUpdate) was generated from the template you have provided.

When I used this simple code to generate file from your template issue doesn't occur. Could you please test it on your site and let me know how it works for you.

string templatePath = @"C:\source\TestFiles\TocUpdateIssueTemplate.docx";

        string outputPath = @"C:\source\TestFiles\DocFromTemplate.docx";

        MemoryStream memoryStream;

        using (memoryStream = new MemoryStream())

        {

            using (WordprocessingDocument generatedDoc = WordprocessingDocument.CreateFromTemplate(templatePath, false))

            {

                MainDocumentPart? mainDocumentPart = generatedDoc.MainDocumentPart;`

                generatedDoc.Clone(memoryStream);`

                File.WriteAllBytes(outputPath, memoryStream.ToArray());

            }

        }

Hi Mariusz,

Thank you for your response, while your approach does work unfortunately our application is a bit more involved since the basis of it allows the user to import data from multiple datasources and output to different formats (office, pdf, html, etc) so we build our own internal document object model and then manually write out elements depending on the format. Is there anything wrong with the ooxml that we produce that could possibly cause the weird behavior of the color being switched upon "Update Fields" being clicked?

This code is just blindly copying the file, so of course the file behaves the same. We are creating a new docx by writing out our OOXML that we need to have this same behavior.

Hi Mariusz, we discovered that the Table Of Figures style is applied to these tables every time they are updated. By setting the correct formatting on that style we were able to prevent the formatting change on update.

Hi @Matt Binsfeld I am glad to hear that you managed to resolve the issue. It is interesting that "table of figures" had effect on colour change because as I can see it was set to blue as well but is more likely because is based on paragraph.
Thank you for letting me know I will close the issue on our end. All the best
