We have tried rendering the provide Word document using the latest version of GroupDocs.Viewer for .NET but could not reproduce the customer’s issue at our end. Please download the rendered output for reference. Could you please ask the customer to share the version of GroupDocs.Viewer for .NET that he is using?

Kind regards,



We have checked the customer’s issue with v18.12 as well but could not reproduce it at our end. The sample application that we have used can be downloaded from here as a reference. The application renders the sample.docx document and saves the results in the Storage folder which is located in the root directory. If possible, please ask the customer to share with us the complete source code (without compilation errors) that can be used to replicate the issue.

After a detailed investigation, we observed that API is rendering the second page of the document without any issue, see page_2. However, the reported issue was reproduced when we merged the generated HTML pages into a single HTML file, see merged page_2 (the complete rendering results can be downloaded from here). Therefore, it is necessary to confirm it from the customer whether he is merging the HTML pages into a single HTML file or he might have been rendering/embedding the HTML pages altogether in his web page. Once confirmed, we would be in a better position to provide the solution.

Dear team,
Thanks for your reply!

Our customer just use the “Get Page” function to get pages totally then add each page into it.
Also the pages you create also have appearing problem after the first page, those tables are losing some words or just empty.
Please kindly help us check again and fix it.

Thank you, waiting for your reply!

We confirm that customer’s issue is reproduced when we add the rendered HTML pages into the single HTML file or display on a web page. We have logged it in our Issue Tracking System with ID: VIEWERNET-2091 to investigate it further.

As a workaround, you can display or embed the rendered HTML pages within the iframe tag and it will resolve the issue. You can download this sample application which renders the document and generates the combined HTML file (in .\Storage\ folder) by adding the rendered HTML pages using iframes (download output). Hope it helps.
