Table cells vertical borders lost on docx export

[stim]

Hi,

Table cells with individually set vertical borders lose them when DocxFormatProvider is used for export. Import and export the attached file to see the problem. Does anyone know how to fix this? Pdf export seems to work correctly.

Thanks,

Hi, Stim,

The following KB article is quite useful on this topic: Saving DOCX to PDF Removes Table Borders

In a similar way you can also apply the cell borders. Please give this approach a try and see how it works on your end.

I hope you find this information helpful. Please, let me know if there is anything else I can assist you with.

Hi, Dess,

When the document is imported (as a template for further processing) the cell borders are there in the created RadFlowDocument object. They disappear when the Export method of DocxFormatProvider is called. I know the trick you pointed out and it doesn't help. Specifically, I tried this for test:

                    foreach (Section section in document.Sections)
                    {
                        foreach (var block in section.Blocks)
                        {
                            Table table = block as Table;
                            if (table != null)
                            {
                                foreach (var row in table.Rows)
                                {
                                    foreach (var cell in row.Cells)
                                    {
                                        cell.Borders = new TableCellBorders(new Border(1, BorderStyle.Single, new ThemableColor(Colors.Black)));
                                    }
                                };
                            }
                        }
                    }

The result is in the attached file.

Hello Stim,

Dess is currently absent so I will be taking over for her for the time being.

As a start, I would first like to mention that I tried reproducing the described behavior on my end however the results seem to be as expected and all borders are intact. I am testing in both .NET Framework and .NET Standard with the latest Document Processing version 2024.2.426, but the results seem to be the same with older versions as well.

Perhaps there is something I am missing so would you be able to address as many of the following points as possible in order to provide more context to the scenario?

• The project environment (.NET Framework / .NET Standard / .NET Core).
• The used Document Processing version.
• Are you doing any additional processing of the document?
• Attach a possible code snippet or a project that can help reproduce the issue.

While sharing resources please keep in mind that because of the nature of the Q&A Forum anything shared here will be accessible to the public.

Thank you in advance for your cooperation.

Hi,

Currently, we use Net Framework 4.7.2, KendoUI MVC 2023.2.829.545 (installed March this year; the working version was 2020.1.219). After opening, we do process the document, but it doesn't matter. To see the error, it is enough to just open the previously attached Example.docx file and save it without any processing using DocxFormatProvider..

Hello Stim,

Thank you for the provided context details. I was able to reproduce the disappearing borders on my end as well. This issue appears to be a regression that has already been fixed as it does not reproduce with previous or newer versions of Document Processing.

If it fits your scenario I would advise you to upgrade to an even newer version of the product as it will include improvements and additional features however you can also regress to a lower version where the issue does not reproduce.

Please excuse us for the inconvenience and thank you for your understanding.
